Components of an AMSOIL Synthetic Nano Fiber oil filter

Ea Motorcycle Oil Filters

Ea Motorcycle Oil Filters feature a specially constructed silicone anti-drainback valve (where applicable) and a nitrile sealing gasket to go along with the full-synthetic media. The anti-drainback valve provides excellent protection during startup and remains flexible in all temperatures. The nitrile sealing gasket resists chemical breakdown, providing excellent durability and ensuring long filter life.


Superior Filtration

The unique construction and full-synthetic media of AMSOIL Ea Motorcycle Oil Filters allow them to provide excellent performance in motorcycles and other powersports equipment. They are designed to last longer, stop smaller dirt particles and offer less restriction than other filters. Ea Motorcycle Oil Filters provide filtering efficiency of 98.7 percent at 20 microns, delivering absolute efficiency for motorcycles.


Superior Alternative, Multiple Applications

AMSOIL Ea Motorcycle Oil Filters provide outstanding protection for motorcycles, ATVs, four-stroke personal watercraft, four-stroke snowmobiles and four-stroke outboards. AMSOIL provides Ea Motorcycle Oil Filters for the most popular powersports applications.


Ea Motorcycle Oil Filter Service Life

For maximum engine protection, AMSOIL recommends changing Ea Motorcycle Oil Filters at every oil change.







Ea Motorcycle Air Filters

Ea Motorcycle Air Filters feature pleated filtration media with epoxy-coated wire on the face and back for additional strength and stiffness. High-quality plastisol potting compounds bond the pleat packs to the plastic or aluminum side plates.


Superior Filtration

The synthetic nanofiber media featured in AMSOIL Ea Motorcycle Air Filters has sub-micron diameters and small inter-fiber spaces, resulting in more contaminants being captured on the surface of the media and lower restriction. Cellulose, wetted-gauze and foam filters have larger spaces between the media that cause contaminants to load in the depth of the filter, resulting in higher restriction and lower capacity.


Ea Motorcycle Air Filter Service Life

AMSOIL Ea Motorcycle Air Filters are cleanable, providing long service life. They should be cleaned every year or according to operating conditions. Operation in extremely dusty or dirty environments may require more frequent cleaning. Ea Motorcycle Air Filters should be changed every four years.
