Polyester Mesh Bags Prevent Loss of Air Flow and Horsepower in Racing and Off-Road Applications
AMSOIL Ea Pre-Filters (Product Code: EaPF) are for racing and off-road applications. These polyester mesh bags fit over the top of existing air filters to prevent large particles from sticking to the filter and blocking the flow of air, preventing the loss of horsepower. AMSOIL Ea Pre-Filters are oil-free, so 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 at the mill, not sprayed on, so there is no loss of air flow.
- Polyester mesh bag with industrial grade elastic band
- Bag will not block air flow
- Prevents loss of horsepower
- Easily removed and shaken free of debris in seconds
- Oil-free – dirt will not stick to bag and create loss of air flow and horsepower
- Treated with water repellent at the mill – not sprayed on, which can result in loss of air flow (list below shows which filters contain this treatment)

What Are Pre-Filters?
AMSOIL Ea Pre-Filters fit over the top of existing air filters. These polyester mesh bags features an industrial grade elastic band at the opening to ensure the pre-filter does not slide off.
Why Use A Pre-Filter?
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.
Oil-Free Woven Mesh Bag Prevents Loss of Air Flow and Horsepower
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 inch from getting to the air filter without significantly reducing air flow. Particles larger than 0.005 inch 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 Ea High-Performance Racing Air Filters and AMSOIL Ea Induction Cold Air Intake Filters allow more air flow than the engine can process, so adding an AMSOIL Ea Pre-Filter will not prevent a more-than-adequate amount of air flow from entering the engine.
To clean AMSOIL Ea Pre-Filters, shake off any excess dirt and, if necessary, soak in soapy water. After soaking, agitate the Ea Pre-Filter to remove any remaining debris and grime, shake off any excess water and air dry.
- For racing applications, inspect pre-filter at every race to determine whether or not they require cleaning.
- For regular applications, pre-filter should be cleaned every 3,000 to 5,000 miles.
AMSOIL Ea Pre-Filters should be changed every six to twelve months, or as conditions dictate.
