Product Description
EaPF filters
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?
Ea Pre-Filters fit over the top of existing air filters. These polyester mesh bags feature an industrial grade elastic band at the opening to ensure the pre-filter does not slide off.

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 EaPF
AMSOIL Ea Pre-Filters are constructed with woven mesh that contains uniformly-sized openings. They are oil-free, so the dirt will not stick to the bag and create a loss of air flow and horsepower. Several Ea Pre-Filters are treated with a hydrophobic water repellent process that helps prevent moisture from damaging air filters. This proprietary process is done at the mill as the pre-filters are created, not sprayed on, so there is no loss of air flow. While Ea Pre-Filters are effective in repelling water, they are not waterproof.

Ea Pre-Filters prevent particles down to 0.005’ from getting to the air filter without significantly reducing air flow. Particles larger than 0.005’ generally just fall off the pre-filter.

Will Not Block Air Flow
AMSOIL Ea Pre-Filters will not cause any significant reduction in air flow. In fact, AMSOIL EaAU and EaAR Filters allow more air flow than the engine can process, so adding an EaPF will not prevent a more-than-adequate amount of air flow from entering the engine.

Cleaning Instructions
To clean AMSOIL Ea Pre-Filters, shake off any excess dirt and, if necessary, soak in soapy water. After soaking, agitate the EaPF to remove any remaining debris and grime, shake off any excess water and air-dry. Ea Pre-Filters used in racing applications should be inspected after every race to determine whether or not they require cleaning. Ea Pre-Filters used in regular applications should be cleaned every 3,000 to 5,000 miles. AMSOIL Ea Pre-Filters should be changed every six to 12 months, or as conditions dictate.
