Amsoil By Pass Oil filter
The Ea Amsoil 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 filter, the AMSOIL Ea By-Pass Filter operates by
filtering oil on a “partial-flow” basis.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK21 By-Pass Filtration
System.
AMSOIL now offers new 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 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 By-pass 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 Bypass 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 new 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 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/bypass 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.
