BMK34 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.

*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 link above for more information.

*Please call (800) 956-5695 M-F, 7 a.m.-7 p.m. Central to order the optional aluminum filter adapter (BK1104).
