PRODUCT DESCRIPTIONAMSOIL Ea By-Pass Oil Filters (EaBP) provide the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine?s full-flow oil filter, AMSOIL Ea By-Pass Filters operate by filtering oil on a ?partial-flow? basis. They draw approximately 10 percent of the oil pump?s capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can?t remove. The AMSOIL Ea By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.Higher EfficiencyAMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. Longer LastingWhen used in conjunction with AMSOIL motor oil and an AMSOIL EaO or Donaldson Endurance? filter, the EaBP Filter should be changed every other full-flow filter change up to 60,000 miles.By-Pass Filtration Benefits ?
