BMK31 Installation and Servicing Instructions

The 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.

Note: This bypass system does not fit Ford E-series engine installations, nor applications found in larger trucks or buses. Contact Technical Services to confirm before ordering if you have any questions.
