BMK-23 Dual Bypass KitThe 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 full-flow 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.

The Universal Dual Remote Bypass provides superior filtration performance by combining the full-flow and bypass filters on a single mount. System includes mount, mounting hardware, hose and hose fittings. Note: The spin-on adapter, EaO26 full-flow oil filter, and a Bypass oil filter are each sold separately. EaBP120 will not work with this system. You must purchase the spin-on adapter that matches the filter thread size on your vehicle (see table below)
