AMSOIL Air Filters

For racing and off-road applications.

AMSOIL EaPF Pre-Filters

AMSOIL now offers Ea Pre-Filters (EaPF) for racing and off-road applications. AMSOIL Ea Pre-Filters prevent large particles from sticking to EaAR and EaAU Filters and blocking the flow of air.

What Are Pre-Filters?

Are you looking forward to boosting the mileage on your vehicle? AMSOIL PI Performance Improver will do just that for your gasoline engines.

Why Use Pre-Filters?

Racers and off-road enthusiasts subject their vehicles to some of the most severe conditions possible. These vehicles operate in areas of heavy dirt and mud that gets slung into every crack and corner, often clogging air filters. AMSOIL Ea Pre-Filters are designed to keep larger particles from getting into and clogging the pleats of air filters. When an air filter is clogged, the engine loses horsepower and, in the case of Ea Air Filters, the filter must be cleaned. There is no vacuum or compressed air available on the race track or out in the swamp, but an Ea Pre-Filter is easily removed and shaken free of debris in seconds.

AMSOIL Ea Carbureted Engine Air Filters & Kits

AMSOIL Ea® Racing Air Filters (EaAR) are specially designed for racing and street rod enthusiasts who desire AMSOIL quality and protection in carbureted applications. AMSOIL Ea Racing Air Filters are constructed with nanofiber technology. This synthetic media ranks among the most efficient available and provides better airflow and more capacity than cellulose filters.

Expanded Applications

AMSOIL custom Ea Racing Air Filter assemblies are designed for racing applications. They incorporate high-performance design and excellent airflow in addition to the high efficiency afforded by AMSOIL Ea synthetic technology. These custom-engineered air filters are designed for use with carbureted engines that use a 14" round air-cleaner housing. The kits feature the common 14" diameter carburetor plate, air filter and high-airflow lid along with a 2", 3", 4", 5" or 6"-high filter. Replacement filters, airflow lids and carburetor plates are also available individually.

Advanced Filtration Technology

AMSOIL Racing Air Filters are designed to replace stock cellulose, oil-wetted gauze or foam filters. The synthetic fibers in Ea Racing Air Filter media have sub-micron diameters and small inter-fiber spaces, resulting in more contaminants being captured on the surface of the media. Cellulose, wetted gauze and foam filters are larger and have larger spaces between the fibers in the media, causing contaminants to load into the depth of the filter, plugging the airflow path and resulting in higher restriction. Ea Racing Air Filters have more pores per square-inch (higher pore density), allowing for higher dirt-holding capacity and lower pressure drop when compared to traditional filter media. Their thinner media fibers produce more uniform pore size distribution, improving the filter's overall ability to capture and retain particles.

WIX Air Filter

Panel element air filters have a linear path through the filter for low airflow restriction & an exclusive pocket pleat for the filter media. Radial air filters are constructed of mesh screen on the inside wall diameter for element strength and media protection from backfire. Use PART NUMBER drop down to select filter.

A History of Excellence

WIX is well-known around the world for its innovative filtration products for the automotive and light truck market. Founded in 1939, the Gastonia, N.C., company earned acclaim during World War II when it created an oil filter out of a paper tube, wooden plugs and yarn when steel was in short supply. In 1954 WIX created the revolutionary spin-on oil filter that was eventually adopted as original equipment on most vehicles.

Today WIX manufactures some of the best oil, air, lube, cabin air, hydraulic, fuel, crank case breather and transmission filtration products on the market. The company is also widely known for its support of NASCAR.
