Cummins 5.0/5.9/6.7L Single-Remote Bypass System provides superior filtration performance for 2004 to current Cummins 5.0/5.9/6.7L engines while working in conjunction with the engine's full-flow oil filter. This system connects to the engine through a full-flow filter adapter and oil fill port. System includes mount, mounting hardware, EaBP90, hose and hose fittings. Note: Full-flow filter not included with this system. Nissan's 5.0L Cummins requires the optional BK1104

The Ea Bypass 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 Bypass 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 fullflow 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.
*Notice: System does not include oil filter adapter. Check top of full-flow oil filter housing for two plugs. System includes fitting options to replace one plug. If both plugs are not accessible, order optional part BK1104. See BMK34 Installation and Servicing Instructions below for more information.
Oil filtration is critical to engine life. Abrasive particles in dirty oil can quickly destroy critical components and ruin precision clearances in an engine if not removed through filtration. Today’s engines, however, are designed with smaller, lower-capacity oil filters which are harder to get to for servicing. This means less efficient filtration and a reluctance to change filters at regular intervals, leading to a build-up of dirt in the oil.
The AMSOIL Single Remote Oil Filtration System is designed to provide superior filtration efficiency, increase oil capacity and improve oil filter accessibility.
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 Filtration Efficiency
A vehicle’s regular oil filter is a fullflow filter. This means that all the oil pumped by the engine must pass quickly through the filter before it reaches the engine. This high flow demand limits the size of particles conventional filters can effectively remove. Particle size is measured in units called microns.
A decent full-flow filter will effectively remove particles down to about 25 microns. But studies have shown that over 60 percent of all engine wear is caused by particles in the 5 to 20 micron range. AMSOIL Ea By-Pass Oil Filters remove particles less than one micron, keeping the oil free of virtually all wear-causing particles.
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.
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.
Increased Filter Size
Many auto manufacturers have been using smaller full-flow filters to help squeeze their engines into tighter engine compartments. But reducing a filter’s size severely limits its service life and contaminant-holding capacity.
A single remote by-pass system addresses all the filtration requirements for extended engine and oil life in an economical way.
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.

28 Years and going strong
My D-250 4 wheel drive truck vintage 1991 has passed the 1,346,000 KM mark and is going strong. No repairs to the motor have been done aside from normal maintenance, such as injectors, valve adjustment etc. .
At 34,000 Km the engine lubrication was switched to Amsoil including the bypass oil filtration 110 bypass system. Oil changes were done every 2 years and the oil filters annually.
