AMSOIL Ea By-Pass Oil Filters (EaBP) provide the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-ﬂow oil filter, AMSOIL Ea By-Pass Filters operate by filtering oil on a "partial-ﬂow" basis. They draw approximately 10 percent of the oil pump’s capacity at any one time and trap the extremely small, wear-causing contaminants that full-ﬂow filters can’t remove. The AMSOIL Ea By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
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.
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson Endurance™ Full-Flow Filter, EaBP Filters 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, EaBP Filters should be changed every other full-ﬂow filter change. AMSOIL recommends using oil analysis when extending oil drain intervals.
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.
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. According to ISO 23556 testing, 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.

AMSOIL offers by-pass components (sold separately) 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/6.4L Power Stroke™ Diesels -- To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L and 6.4L Power Stroke™ diesel engines, AMSOIL offers the new Aluminum Billet Oil Filter Cap (BK1101), the Aluminum Billet Oil Fill Cap (BK1102) and the 90-degree JIC Elbow (BP242, two recommended) (all sold separately). 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), for 6.7L Cummins engines use (BK1302), and the 90-degree JIC Elbow (BP242) (all sold separately). 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) (all sold separately)
