Air Filters

Make an AMSOIL air filter your first line of defense against wear-inducing particles entering your engine. Unrestricted air flow to the engine must occur for efficient combustion to take place. Engines “breathe” roughly 9,000 gallons of air for every gallon of fuel burned. If dirt isn’t stopped from infiltrating, engine performance power, fuel efficiency and longevity can be severely compromised. AMSOIL is proud to make their own lines of air filter available, Absolute Efficiency (Ea lighter duty) and PowerCore (heavy duty). Choose from EaA, EaAU, EaAR and EaPF types of AMSOIL air filter, depending on your application (they have been developed as car, light truck, ATV, recreational vehicle and motorcycle air filters). They have superior efficiency and capacity; for example, AMSOIL EaA air filters are all cleanable and reusable, and remain effective up to 25,000 miles or one year before cleaning is required. Overall service life is 100,000 miles or 4 years.

Not only does AMSOIL offer its own high quality air filters, but we also carry supplemental brands such as Donaldson air filters, Hastings air filters and WIX filters. Browse the other products we carry (including Trico wiper blades) by clicking on the category links to the left.
