REPLACEMENT FOAM FILTER FOR WRX & STI - 08-21 WRX, 08-21 STI

Two Piece Design: PERRIN Performance filters feature a unique two piece design allowing the user to remove the foam filter element for easy cleaning. Easily run the element under a faucet for cleaning and ring out by hand. Simply slip the foam sleeve back over the filter frame and your ready to go.

Open Cell Foam Element: PERRIN foam filters are made of reticulated polyurethane foam which offers a minimal air restriction. The filter element is sprayed with a special oil that adheres to the foam making the poly matrix sticky to retain dirt. Foam filters do not block dirt, they grab it, suffering only minimal drops in air flow as they filter dirt, maintaining air flow levels when other filters would clog.

Clean and Protect: Remove months of oil and grime by simply spraying on this easy to use cleaner. Just let it sit on the filter element for a few moments and simply rise in the sink. Once your filter is dry, just spray on a fresh coat of oil and you are ready to go.

Construction: The Pre-filter is constructed with a proprietary polyester mesh with uniform micron openings. The mesh is UV resistant, and can withstand heat up to 450 degrees. The material is puncture resistant and has elasticity characteristics allowing the threads to return to the original position in the event the threads have been impacted or shifted.
