Need a cross reference for amsoil filter EaBP90 to purolator?

Answer 1

There likely isn't one since the AMSOIL EaBP90 filters smaller particles, holds more particles, lasts longer, and flows better than the Purolator. Apples and Oranges.

Tim is correct.

Purolator filters are unable to provide the protection the EaBP90 can.

PRODUCT DESCRIPTION

AMSOIL 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 Efficiency

AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes.
