Master Filter Cross-Reference Guide

Absolute Efficiency
AMSOIL Ea Oil Filters (EaO, Ea15K) have one of the best efficiency ratings in the automotive/light-truck market. Ea Oil Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns, while competitive filters containing conventional cellulose media range from 40 to 80 percent efficiency.

Less Restriction
AMSOIL Ea Oil Filters have lower restriction than conventional cellulose media filters. Their small synthetic nanofibers trap smaller particles and hold more contaminants, resulting in lower restriction. During cold-temperature warm-up periods, an Ea Oil Filter allows the oil to flow through the filter more easily than a typical cellulose filter does. Lower restriction decreases engine wear.

Contaminant Retention
A filter’s capacity refers to the amount of contaminants it can hold and still remain effective. AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing filter lines do. In fact, when used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for up to 15,000 miles/one year, whichever comes first, or 25,000 miles/one year, whichever comes first, depending on application and severity of service.

Superior Construction
AMSOIL Ea Oil Filters are made with premium-grade full-synthetic media. The strictly controlled processing of this media ensures accurate filter construction and is what allows Ea Oil Filters to deliver higher capacity and efficiency along with better durability.

Over the service life of a conventional cellulose filter, hot oil will degrade the resins that bind the media. Ea Oil Filters’ full-synthetic media technology is resin-free. It uses a wire screen backing that is pleated with the media for superior strength.

Ea Oil Filters are constructed with HNBR gaskets that are fully tested to extreme distances in numerous severe environments. The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting, premium-grade silicone anti-drain valve.

Applications And Recommendations
AMSOIL Ea Oil Filters provide superior oil filtration for cars and light trucks.

Service Life
When used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for extended service life:

• Ea Filters designated with product code Ea15K are recommended for 15,000 miles/one year, whichever comes first, in normal or severe service.

• Ea Filters designated with product code EaO are recommended for 25,000 miles/one year, whichever comes first, in normal service or 15,000 miles/one year, whichever comes first, in severe service.

Consult the AMSOIL Online Application Guide or MyAMSOILGarage™ at www.amsoil.com to determine the appropriate filter for each application. When AMSOIL Ea Oil Filters are used with a motor oil other than an AMSOIL extended drain motor oil the filter should be changed according to the vehicle manufacturer recommendation.

No matter what kind of riding you do, there's an AMSOIL EaOM Motorcycle Oil Filter that's right for your bike or ATV.

Look Up the AMSOIL EaOM Oil Filter for your Motorcycle or ATV

See product application notes for Harley Davidson Motorcycles at bottom of page

Oil is the life blood of your motorcycle engine. Your oil filtration system keeps that life blood flowing and your ride on the road.

For nearly 30 years, AMSOIL INC. has offered state-of-the-art products Dealers can sell with pride. In that time, the company's reputation has grown, along with its product line.

Now, AMSOIL has developed a full line of oil filters specifically designed for motorcycles and ATVs.

The SuperDuty Motorcycle Oil Filters (SMF) reflect the newest technological advances in the quest to meet the unique demands of today's high-stress motorcycle engines.

The three main functions of any oil filter are flow, life and efficiency.

  • Flow is the filter's ability to let the right volume of oil reach its intended parts, with a minimum degree of restriction.
  • Life is the filter's capacity to remain in service for a predicted amount of time.
  • Efficiency is the filter's ability to remove contaminants that cause engine wear.

While each of those functions is vital individually, there's more to it.

"Remember, it's more than just flow. It's more than just efficiency. It's more than just life," said Dave Anderson, AMSOIL Technical Sales Director. "They all have to perform in unison. A filter is only as good as its weakest link."

Typically, oil filters are comprised of cellulose, or paper, synthetic fibers, glass fibers, or a combination of media.

"All of these fibers have a different set of characteristics to them," Anderson said.

Each provides different levels of filtration of the damaging dirt and dust particles that shorten the life of a motorcycle engine.

  • Traps Dirt Throughout Media Thickness
  • Up to 100% More Capacity
  • Up to 20% More Efficiency
  • Built for Rugged Performance
  • Heavy-duty Steel Case Withstands Extreme Conditions
  • Assures Oil Flow With Relief Valve
  • Prevents Oil Drainage During Engine Shutdown

Flow is gained through a media that is open and free, while efficiency is gained through media that is closed and difficult to penetrate. The flow versus efficiency " compromise within the filtration system is the greatest demand on an oil filter's performance.

"Through our testing, we have found the best for motorcycles, and automobiles, is a blend of the three media - synthetic, cellulose and glass," Anderson said.. "That gives the best overall performance. You have to look at overall performance. How they do all the tasks that you want them to do. A prudent consumer must consider the total package."

AMSOIL SuperDuty Motorcycle Oil Filters provide the greatest possible balance of that "total package" to provide the ultimate in overall filtration performance.

The filters are available in black finish, with several models also available in chrome. The chrome models have a C designation.

They have a heavy-duty case of drawn steel. The case is double-crimped at the base with rolled-under seaming to withstand extreme pressure surges and road shocks.

AMSOIL SMF are available in spin-on and cartridge types.

The new G-194 Automotive Filter and Cross- Reference Guide lists the correct filter for each motor- cycle and ATV. A separate Motorcycle and ATV Filter Cross Reference Guide, G-1768, at $1.00 U.S., also is newly available for your convenience.

These quality full-flow filters are designed to allow extended filter change intervals.

AMSOIL INC. recommends the following guidelines. When using an AMSOIL SMF with conventional oil, change the filter at the manufacturer 's recommendation. When using an AMSOIL SMF with AMSOIL Motor Oil, change the filter at twice the manufacturer 's recommendation or six months.

PRODUCT DESCRIPTION
The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK21 By-Pass Filtration System

AMSOIL offers by-pass components to ease the installation of the BMK21 By-Pass Filtration System in three popular diesel engines: the Ford 6.0L Power Stroke™, the Dodge 5.9L Cummins and the General Motors 6.6L Duramax.

Engine compartments are becoming increasingly cramped, leaving little room for after-market additions and improvements. The BMK21 is a single remote by-pass filter system that fits into much smaller spaces than the AMSOIL Dual-Remote By-Pass System.

Ford 6.0L Power Stroke™ Diesels
To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L Power Stroke™ diesel engine, AMSOIL provides the new Aluminum Billet Oil Filter Cap (BK1101), the Aluminum Billet Oil Fill Cap (BK1102) and the 90-degree JIC Elbow (BP242). These new high-quality billet aluminum caps replace the original equipment manufacturer (OEM) filter cap and oil fill cap. The new caps have holes tapped in them that accept the JIC elbows for hose connectors.

Dodge 5.9L/6.7L Cummins Diesels
To ease installation of the BMK21 in later model Dodge pickups equipped with the 5.9L and 6.7L Cummins diesel engine, AMSOIL offers the 1/8" NPT - 1/4" JIC fitting (BP241), the Aluminum Billet Oil Fill Cap for Dodge 5.9L Cummins diesels (BK1301) and the 90-degree JIC Elbow (BP242). The BP241 fits onto the existing plug on top of the OEM full-flow filter mount, and the addition of the BK1301 eases the installation of the oil return line.

General Motors 6.6L Duramax Diesels
To provide GM Duramax owners the same ease of installing the BMK21, AMSOIL is now offering an oil filter “Sandwich” adapter (BK1201).

The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK11 back to the engine. To complete an installation, the following components must be purchased separately:

1. Aluminum oil filter Sandwich Adapter with o-ring (BK1201)
2. Aluminum Billet Oil Filler Cap for GM Duramax (BK1202)
3. Two 90 degree JIC Elbows (BP242)
4. Single Remote By-pass system (BMK21)
5. By-pass filter (EaBP90, EaBP100, or EaBP110, as space dictates)

Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes.

Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity along with superior corrosion resistance. AMSOIL EaBP Filters have a marine powder coated exterior; and their zinc-dichromate base plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two stage pleated and layered cellulose/full synthetic media has an efficiency rating of 98.7 percent at two microns.

Longer Lasting
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson Endurance™ filter, the EaBP should be changed every other full-flow filter change up to 60,000 miles. When used with other brands of motor oil or full-flow filters, the EaBP Filter should be changed every other full-flow filter change. AMSOIL recommends using oil analysis when extending oil drain intervals.

Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on clean oil. Engine efficiency is increased, providing extended engine life.

Soot Removal
AMSOIL has designed a high-efficiency by-pass filter element that is also a soot removal device. AMSOIL Ea By-Pass Filters use a synthetic/cellulose sandwiched media. The inner layer of the element is composed of a highly efficient cellulose media covered with a full synthetic media outer layer. These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.

By-Pass Filtration Benefits

• Dramatically Extended Drain Intervals
• Improved Oil Cooling
• Increased Filtration Capacity and Life
• Increased Fluid System Capacity
• Efficient Small Particle and Soot Removal
• Significantly Extended Engine Life
• Equipment Constantly Runs on Clean Oil
• Increased Engine Efficiency
• Remove Particles Less Than One Micro

Dual Remote Filter System
The AMSOIL Dual Remote Oil Filtration System converts an engine’s full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount. The Dual Remote System provides superior filtration efficiency, increased oil capacity and improved oil filtration accessibility. See the G1092 brochure for more info on the Dual Remote Filtration System.

IMPORTANT NOTICE
Read all instructions completely before attempting to install this unit. Improper installation could result in serious system and/or equipment damage. The installation of this system is not difficult, however, some mechanical ability is necessary. If you are not comfortable with the instructions or have questions, do not attempt to install this system. Consult a mechanic or contact AMSOIL INC. for further instructions or assistance.

If installing on a Japanese- or European-built vehicle utilizing Metric or B.S.P. threads, additional parts may be required. Consult step 0.1 before you continue.

WARNING: This filter system is not designed to replace the engine's normal full-flow filter. Do not attempt to install a by-pass filter element in place of the existing full-flow filter.

WARNING: Extreme care should be taken to avoid bodily harm during installation. Before starting, ensure the engine is cool to avoid burns and never work in the engine compartment area with the engine running.

A. Getting started
1. Check all parts against the parts list and inspect for damage.

2. Make sure you have the tools needed for the job.

Recommended tool list

5/16" Allen wrench
Torque wrench
Drill
7/16" wrench (2)
Hammer
1/4" drill bit
7/8" wrench
Center punch
Adjustable filter wrench
9/16" wrench

3. Because of the wide range of possible mounting configurations, hose and hose fittings are not provided with this mount. Hose should meet or exceed SAE-100R6 specifications, and have a minimum inside diameter of 1/4". The mount itself has 3/4"-16 straight threads and the adapter fittings provided are 3/4"-16 straight x 1/4" JIC. Read through instructions and determine which plumbing arrangement best fits your application. Purchase hose and fittings according Make certain hose fittings match the type of hose chosen. Note: Hose and hose fittings are available from AMSOIL and your local AMSOIL Dealer. Refer to diagram D below and the parts list for 1/4" components matched for use with this system.

Diagram D Installation Drawings - Click On Images For Larger View

B. Filter selection
Any of the 3 different sizes of the AMSOIL Spin-On By-Pass Oil Filter elements may be used with this mount. Select the element size according to your vehicle's oil capacity.

Vehicle Oil Capacity Recommended Element
15 to 18 quarts use two EaBP-90
15 to 30 quarts use two EaBP-100
15 to 42 quarts use two EaBP-110

Service recommendations for these filters are listed later in these instructions. Selecting a larger filter than recommended will extend the service interval, while selecting a smaller filter than recommended will shorten the service interval.

C. Attaching the filter mount

1. Survey the engine compartment for possible mounting locations. Solid structures such as the firewall, fender well, radiator support or frame are normal locations. Refer to diagram A for minimum area requirements and consider accessibility for servicing.

2. Note that the filter mount can be rotated 180° in its mounting brackets. This allows the oil supply and return hoses to enter the mount on either the right of left hand side. Choose the side that will minimize the need for bends in the hoses or additional hose fittings. Refer to diagram B for preferred mounting positions.

3. When the location has been determined, use the mounting template provided to locate and mark mounting holes. This can be easily done with a center punch and hammer.

4. With a 1/4" drill bit, drill out the previously marked mounting holes and attach the two piece mount bracket. Use the 4 -1" long 1/4" bolts, nuts, small washer and fender washers provided. Note the assembly diagram D for details. Using two 7/16" wrenches or socket, tighten to 8 foot pounds.

5. Apply thread sealant onto the "0" ring adapter fitting (BP-213) and the restriction assembly (BP-202) as noted in diagram C. Install the "0" ring adapter fitting (BP-213) in the mount end adjacent to the arrows pointing IN. Install the restriction assembly (BP-202) in the mount end adjacent to the arrow pointing OUT. Using a 7/8" wrench, tighten both fittings to 40-43 foot pounds.
Warning: The system is designed for partial/by-pass oil flow. Failure to install the restrictor assembly (BP-202) can result in serious equipment damage.

6. Apply thread sealant as noted indiagram C to the Allen head "0" ring plugs (BP-191). Using a 5/16" Allen head wrench, install plugs in remaining mount ports and tighten to 40-43 foot pounds. Note: If optional oil sampling valve is to be used, refer to diagram D and install in place of either Allen head "0" ring plug.

7. Attach the filter mount to the mounting brackets using 4 - 1-1/2" long 1/4" bolts, nuts and washers provided. Warning: The bolts must be installed so that the nuts are on the side opposite the filter nipples. Failure to do this will result in the bolts hitting the oil filters. Using two 7/16" wrenches or socket, tighten to 8 foot pounds.

D. Oil Supply
1. Usable oil pressure sources are available on many engine blocks. There are openings into the oil channel through the side of the block and in the area of the existing oil filter(s). Make sure it is an oil pressure opening by replacing the plug with a gauge and turning the engine over, or by turning the engine over with the plug out and watching for increased flow. DO NOT START ENGINE WITHOUT PREPARATION TO CONTROL THE OIL FLOW. Install appropriate fitting to accept your hose connector.

2. An alternate installation is to use the existing oil pressure sending unit. Remove the oil pressure sending unit and install a street tee. Then re-install the sending unit in one arm of the tee. Note: With this installation a slightly lower oil pressure reading may register, indicating oil flow to the by-pass filter. A change of 10% or less is not to be considered significant.

3. Install selected hose and hose fittings between the engine block or the remaining arm of the tee and the filter mount port marked with the arrow pointing IN. Hose should be routed in a manner that avoids contact with sharp or moving parts and minimizes bends. If bends in the hose can not be avoided, make sure the bend is greater than the minimum radius recommended by the hose manufacturer. Note: Bends should not start at the fitting. Refer to diagram E for suggestions on proper hose routing.

4. To maintain hose position, plastic hose ties are advised.

E. Oil Return
1. Existing Porting Options: Most engines have an oil return opening in the crankcase wall or oil pan, usually on the same side as the oil channel pressure opening but somewhat lower. Remove the plug and determine that it is not a pressurized port and offers an unrestricted flow to the oil pan. Install the appropriate fitting to accept your hose fitting. Attach and route hose, connecting to the filter mount port marked with the arrow pointing OUT. This should be the same port in which you previously installed the restrictor assembly (BP-202).

2. New Porting Option: Where an installation requires a new hole (in oil pan or valve cover), a self-tapping hollow bolt may be used. (The bolt is available from AMSOIL. Order BP-40 Bolt and BP-41 Sealing Gasket.) Note: The self-tapping hollow bolt should be used on stamped metal components only.

a. For oil pan installation, mark a spot approximately 3" above the bottom of the pan. Avoid any pan formations that may suggest an internal obstruction. For the valve cover, choose a mounting location that will not interfere with the movement of internal components and away from the crankcase ventilation lines.

b. Using a center punch and hammer, punch a hole in the chosen location between 1/4" (.25") and 5/16" (.3125") in diameter. Note: Do not drill this hole as metal fillings are likely to enter the engine and it will pro- duce a weaker attachment of the self-tapping hollow bolt.

c. Using a 9A6" wrench, thread in the self-tapping hollow bolt (BP-40) and sealing gasket (BP-41). As the bolt is tightened, make sure sealing gasket is snug all the way around the bolt. Tighten bolt to 6-8 foot pounds.

d. Install the appropriate fitting to accept your hose fitting. Attach and route hose, connecting to the filter mount port marked with the arrow pointing OUT. Again this should be the same port in which you previously installed the restrictor assembly (BP-202).

3. Other Options: Use a hollow bolt (available locally) to replace a cap screw holding such components as the fuel pump, timing case, or an inspection cover. Remove the selected bolt and determine if it provides an unrestricted passage to the oil pan. If so, install the hollow bolt. Route and connect hose as previously described. You may also use the AMSOIL Oil Return Swivel fitting (BP-89). See additional information on swivel fitting below.

4. Fill the selected AMSOIL By-Pass Filter elements with the same motor oil being used in the vehicle. Lubricate the filter gasket with oil and spin filters onto mount. Tighten one full turn after filter gasket first contacts mount, back off 1/8".

F. Start up procedures
1. Check that all fittings and hoses are securely attached, and that the hoses are routed properly.

2. Check engine oil level. Fill to full mark if necessary.

3. Set vehicle parking brake. With transmission in park/neutral start the engine and immediately check oil pressure. Note: Pressure may initially take a moment or two to rise.
Caution: Carefully check for leaks at fittings, hoses and mount. If leaks are observed, STOP ENGINE IMMEDIATELY, repair leaks and continue.

4. After engine has warmed, shut off and re-check engine oil level. Fill as necessary.

5. Record vehicle mileage/operating hours and date of installation.

G. Periodic maintenance
1. Periodic visual inspection of the fittings and hoses is recommended. Check for leaks, hose deterioration and cuts. Repair and/or replace as necessary.

2. Properly sized, your AMSOIL By-Pass filters will last twice as long as your regular full-flow filters. It is recommended however, filters be changed using an oil analysis program.

3. To change the filter elements:

a. Ensure engine is off and use caution as the engine, oil and filters may be hot and could result in an injury.
b. Using a filter wrench, remove the filter elements. Dispose of properly.
c. Clean the filter gasket contact areas on the mount with a clean lint free rag.
d. Lubricate the new filter gaskets with clean oil or grease.
e. Fill filters as full as possible with engine oil.
f. Screw on new filters, tighten one full turn after filter gasket contacts mount. Back off 1/8".
g. Start engine and check for leaks.

By-Pass Oil Filter Return-Line Fitting

A swivel fitting can be installed directly on your oil filter cap for the oil return-line from the AMSOIL By-Pass Filter. This fitting can be used (in most cases) instead of the self-tapping hollow bolt, which is usually installed on the oil pan. The Return-Line Fitting is made of a sturdy brass-alloy and is constructed so that the top of the fixture can swivel. This makes it easy to take off your oil cap. The installation of the fitting is simple and generally takes 5-10 minutes. Order BP-89. Be sure there is not a crankcase vent in this area.

PRODUCT DESCRIPTION
The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK21 By-Pass Filtration System

AMSOIL offers by-pass components to ease the installation of the BMK21 By-Pass Filtration System in three popular diesel engines: the Ford 6.0L Power Stroke™, the Dodge 5.9L Cummins and the General Motors 6.6L Duramax.

Engine compartments are becoming increasingly cramped, leaving little room for after-market additions and improvements. The BMK21 is a single remote by-pass filter system that fits into much smaller spaces than the AMSOIL Dual-Remote By-Pass System.

Ford 6.0L Power Stroke™ Diesels
To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L Power Stroke™ diesel engine, AMSOIL provides the new Aluminum Billet Oil Filter Cap (BK1101), the Aluminum Billet Oil Fill Cap (BK1102) and the 90-degree JIC Elbow (BP242). These new high-quality billet aluminum caps replace the original equipment manufacturer (OEM) filter cap and oil fill cap. The new caps have holes tapped in them that accept the JIC elbows for hose connectors.

Dodge 5.9L/6.7L Cummins Diesels
To ease installation of the BMK21 in later model Dodge pickups equipped with the 5.9L and 6.7L Cummins diesel engine, AMSOIL offers the 1/8" NPT - 1/4" JIC fitting (BP241), the Aluminum Billet Oil Fill Cap for Dodge 5.9L Cummins diesels (BK1301) and the 90-degree JIC Elbow (BP242). The BP241 fits onto the existing plug on top of the OEM full-flow filter mount, and the addition of the BK1301 eases the installation of the oil return line.

General Motors 6.6L Duramax Diesels
To provide GM Duramax owners the same ease of installing the BMK21, AMSOIL is now offering an oil filter “Sandwich” adapter (BK1201).

The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK11 back to the engine. To complete an installation, the following components must be purchased separately:

1. Aluminum oil filter Sandwich Adapter with o-ring (BK1201)
2. Aluminum Billet Oil Filler Cap for GM Duramax (BK1202)
3. Two 90 degree JIC Elbows (BP242)
4. Single Remote By-pass system (BMK21)
5. By-pass filter (EaBP90, EaBP100, or EaBP110, as space dictates)

Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes.

Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity along with superior corrosion resistance. AMSOIL EaBP Filters have a marine powder coated exterior; and their zinc-dichromate base plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two stage pleated and layered cellulose/full synthetic media has an efficiency rating of 98.7 percent at two microns.

Longer Lasting
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson Endurance™ filter, the EaBP should be changed every other full-flow filter change up to 60,000 miles. When used with other brands of motor oil or full-flow filters, the EaBP Filter should be changed every other full-flow filter change. AMSOIL recommends using oil analysis when extending oil drain intervals.

Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on clean oil. Engine efficiency is increased, providing extended engine life.

Soot Removal
AMSOIL has designed a high-efficiency by-pass filter element that is also a soot removal device. AMSOIL Ea By-Pass Filters use a synthetic/cellulose sandwiched media. The inner layer of the element is composed of a highly efficient cellulose media covered with a full synthetic media outer layer. These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.

By-Pass Filtration Benefits

• Dramatically Extended Drain Intervals
• Improved Oil Cooling
• Increased Filtration Capacity and Life
• Increased Fluid System Capacity
• Efficient Small Particle and Soot Removal
• Significantly Extended Engine Life
• Equipment Constantly Runs on Clean Oil
• Increased Engine Efficiency
• Remove Particles Less Than One Micro

Dual Remote Filter System
The AMSOIL Dual Remote Oil Filtration System converts an engine’s full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount. The Dual Remote System provides superior filtration efficiency, increased oil capacity and improved oil filtration accessibility. See the G1092 brochure for more info on the Dual Remote Filtration System.

To ease installation of the BMK21 in later model Dodge pickups equipped with the 5.9L and 6.7L Cummins diesel engine, AMSOIL offers the 1/8" NPT - 1/4" JIC fitting (BP241), the Aluminum Billet Oil Fill Cap for Dodge 5.9L Cummins diesels (BK1301) and the 90-degree JIC Elbow (BP242). The BP241 fits onto the existing plug on top of the OEM full-flow filter mount, and the addition of the BK1301 eases the installation of the oil return line.

General Motors 6.6L Duramax Diesels
To provide GM Duramax owners the same ease of installing the BMK21, AMSOIL is now offering an oil filter “Sandwich” adapter (BK1201).

The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK11 back to the engine. To complete an installation, the following components must be purchased separately:

1. Aluminum oil filter Sandwich Adapter with o-ring (BK1201)
2. Aluminum Billet Oil Filler Cap for GM Duramax (BK1202)
3. Two 90 degree JIC Elbows (BP242)
4. Single Remote By-pass system (BMK21)
5. By-pass filter (EaBP90, EaBP100, or EaBP110, as space dictates)

Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes.

Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity along with superior corrosion resistance. AMSOIL EaBP Filters have a marine powder coated exterior; and their zinc-dichromate base plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two stage pleated and layered cellulose/full synthetic media has an efficiency rating of 98.7 percent at two microns.

Longer Lasting
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson Endurance™ filter, the EaBP should be changed every other full-flow filter change up to 60,000 miles. When used with other brands of motor oil or full-flow filters, the EaBP Filter should be changed every other full-flow filter change. AMSOIL recommends using oil analysis when extending oil drain intervals.

Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on clean oil. Engine efficiency is increased, providing extended engine life.

Soot Removal
AMSOIL has designed a high-efficiency by-pass filter element that is also a soot removal device. AMSOIL Ea By-Pass Filters use a synthetic/cellulose sandwiched media. The inner layer of the element is composed of a highly efficient cellulose media covered with a full synthetic media outer layer. These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.

By-Pass Filtration Benefits

• Dramatically Extended Drain Intervals
• Improved Oil Cooling
• Increased Filtration Capacity and Life
• Increased Fluid System Capacity
• Efficient Small Particle and Soot Removal
• Significantly Extended Engine Life

AMSOIL Marine Bypass Filtration System

Product Code: 
BMK18
Teaser: 
Offers easily accessible remote mounting capability for a full-flow spin-on oil filter and a spin-on by-pass oil filter. This unique combination of both full-flow and by-pass filtration on a single mounting manifold is the only system of this kind designed specifically for marine applications.

Marine Dual Remote Filtration System
(BMK-18)

The BMK18 is packaged in kit form, which includes the Dual filter mount, mounting hardware, hoses, hose fittings, component parts and installation instructions. In addition, adapter kits of four different sizes enable the BMK18 to be installed on a wide variety of recreational and light commercial marine engines.

Product Description
The Marine Dual Remote Filtration System (BMK18) offers easily accessible remote mounting capability for a full-flow spin-on oil filter and a spin-on by-pass oil filter. This unique combination of both full-flow and by-pass filtration on a single mounting manifold is the only system of this kind designed specifically for marine applications.

Improved Performance
The effects of marine engines running predominantly at or near full throttle after extended periods of non-activity include high operating temperatures and increased potential for wear on engine components. Dual remote filtration is a highly efficient filtering process capable of removing the vast majority of particles in the 5-20 micron range; those that cause the most wear. Dual remote filtration also has the ability to effectively remove particles down to one micron in size. The AMSOIL Marine Dual Remote Filtration System (BMK18) offers a clear advantage by providing better oil filtration, increased oil capacity and longer oil and filter life.

Reduces Heat
The BMK18 requires a one- to two-quart oil volume increase, offering increased oil cooling capabilities. The additional hoses, fittings, filters and aluminum mount assemblies also allow the engine oil to dissipate heat more efficiently as it passes through the filtration system, extending the service life of both the engine and the engine oil..

Outstanding Durability
The Marine Dual Remote Filtration System is designed to be used in harsh marine environments. The hose fittings are coated with a 3 ml layer of Alumiplate™ and 1 ml of zinc and yellow chromate. This Alumiplate coating is 10 times more corrosion resistant than standard zinc and yellow chromate plated fittings. While standard hydraulic fittings typically survive 96 hours in the grueling ASTM B-117 Salt Spray Test, the Alumiplate-coated AMSOIL Marine By-Pass System fittings lasted over 1,000 hours. In addition, the fasteners and mounting bracket are stainless steel and the hoses are U.S. Coast Guard approved.

Fewer Oil Changes
Depending on the boat owner’s hours of use, the improved filtration of the Marine Dual Remote System, along with the use of AMSOIL synthetic lubricants, could completely eliminate oil and filter changes during a typical boating season. With marine engines located in a relatively confined and remote space within the watercraft, ease of filter access and reduced oil spillage are also significant benefits of the BMK18.

Applications
A large number of marine diesel engines have by-pass oil filtration systems installed by the engine manufacturer. Until now, however, this technology has not been available to smaller pleasure boats and light commercial marine applications. The AMSOIL Marine Dual Remote Filtration System was specifically designed for recreational and commercial marine applications that use inboard or inboard/outboard stern drive engines.

The BMK18 is packaged in kit form, which includes the Dual filter mount, mounting hardware, hoses, hose fittings, component parts and installation instructions. In addition, adapter kits of four different sizes enable the BMK18 to be installed on a wide variety of recreational and light commercial marine gasoline-fueled engines, including those manufactured by Chris Craft, Chrysler, Crusader, Evinrude, Johnson, Gray Marine, Mercruiser, OMC, Pleasurecraft, Universal, Volvo Penta and Westerbeke.

The BMK18 kit offers a new heavy-duty, machined aluminum adapter and retaining nut that fits on the existing oil filter mount. Each adapter kit is application specific and must be ordered separately. Consult the Marine Dual Remote Application Guide (G2051) or www.amsoil.com for specific applications. Adapter kits are available for the most popular filter thread sizes. When ordering the BMK18, request one of the following adapter kits:

• BK195 for 3?4" x 16 thread
• BK196 for 13?16" x 16 thread
• BK197 for 18 mm x 1.5 mm thread
• BK198 for 20 mm x 1.5 mm thread

Also, for ease of installation in some applications, optional 90-degree fittings (BK199 and BK200) can be mounted on the filter adapter collar. These parts are also sold separately.

The AMSOIL Marine Dual Remote Filtration System represents the cutting edge of filtration technology, another example of the AMSOIL commitment to providing quality innovations that benefit consumers everywhere.

The remote mount of the BMK18 is compatible with the AMS-Oiler™ Oil Precharger (AMK01). For added engine protection, install the AMK01 to reduce dry starting which is typical of marine engines that sit idle for even short periods of time.

PRODUCT DESCRIPTION
The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK21 By-Pass Filtration System

AMSOIL offers by-pass components to ease the installation of the BMK21 By-Pass Filtration System in three popular diesel engines: the Ford 6.0L Power Stroke™, the Dodge 5.9L Cummins and the General Motors 6.6L Duramax.

Engine compartments are becoming increasingly cramped, leaving little room for after-market additions and improvements. The BMK21 is a single remote by-pass filter system that fits into much smaller spaces than the AMSOIL Dual-Remote By-Pass System.

Ford 6.0L Power Stroke™ Diesels
To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L Power Stroke™ diesel engine, AMSOIL provides the new Aluminum Billet Oil Filter Cap (BK1101), the Aluminum Billet Oil Fill Cap (BK1102) and the 90-degree JIC Elbow (BP242). These new high-quality billet aluminum caps replace the original equipment manufacturer (OEM) filter cap and oil fill cap. The new caps have holes tapped in them that accept the JIC elbows for hose connectors.

Dodge 5.9L/6.7L Cummins Diesels
To ease installation of the BMK21 in later model Dodge pickups equipped with the 5.9L and 6.7L Cummins diesel engine, AMSOIL offers the 1/8" NPT - 1/4" JIC fitting (BP241), the Aluminum Billet Oil Fill Cap for Dodge 5.9L Cummins diesels (BK1301) and the 90-degree JIC Elbow (BP242). The BP241 fits onto the existing plug on top of the OEM full-flow filter mount, and the addition of the BK1301 eases the installation of the oil return line.

General Motors 6.6L Duramax Diesels
To provide GM Duramax owners the same ease of installing the BMK21, AMSOIL is now offering an oil filter “Sandwich” adapter (BK1201).

The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK11 back to the engine. To complete an installation, the following components must be purchased separately:

1. Aluminum oil filter Sandwich Adapter with o-ring (BK1201)
2. Aluminum Billet Oil Filler Cap for GM Duramax (BK1202)
3. Two 90 degree JIC Elbows (BP242)
4. Single Remote By-pass system (BMK21)
5. By-pass filter (EaBP90, EaBP100, or EaBP110, as space dictates)
