Higher Efficiency AMSOIL Ea By-Pass Filters have an efficiency of 98.7 percent at two microns. At normal operating RPM Ea By-Pass Filters will filter all of the oil in a typical five-quart sump in less than 10 minutes.
Superior Construction The superior construction of AMSOIL Ea By-Pass Filters provides better sealing and increased longevity along with superior corrosion resistance.
AMSOIL Ea By-Pass Filters have a marine powder-coated exterior, and their zinc-dichromate base plates increase rust protection. Ea By-Pass Filters feature a nitrile HNBR gasket, an orange silicone anti-drain valve and two-stage pleated and layered cellulose/full-synthetic media.
Longer Lasting When used in conjunction with AMSOIL motor oil and an AMSOIL Ea or Donaldson® Endurance™ Full-Flow Oil Filter, Ea By-Pass Filters should be changed every other full-flow filter change up to 60,000 miles. When used with other brands of motor oil or full-flow filters, Ea By-Pass Filters should be changed every other full-flow filter change. AMSOIL recommends using oil analysis when extending oil drain intervals.
