- Superior small-particle filtration, including soot removal
- Increased filtration capacity and life
- Equipment constantly runs on clean oil
- Helps increase engine efficiency and life
- Helps reduce maintenance costs
- 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 on Detail Page)
Product Overview
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 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.
