Improved oil cooling Equipment constantly runs on clean oil Dramatically extended drain intervals Absolute efficiency of 98.7 percent at two microns Engineered for Outstanding Oil Filtration Efficiency AMSOIL Ea Bypass Oil Filters provide maximum filtration protection against wear and oil contamination. Working in conjunction with the engine's full-flow oil filter, AMSOIL Ea Bypass Filters operate by filtering oil on a "partial-flowbasis. They draw approximately 10 percent of the oil sump's capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can't remove. AMSOIL Ea Bypass Filters typically filter all of the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
