2008+ WRX/STI Panel Filter by Perrin Performance

Don’t let a restrictive OEM paper filter get between you and true performance. The PERRIN Performance„¢ drop-in Panel Filter is the answer for more horsepower. A stealthy approach to higher air flow and an increase in horsepower are a simple install away.

PERRIN dual stage, open cell foam filters are made of reticulated polyurethane foam which offers a minimal amount of air restriction. The filter element is sprayed with a special oil that adheres to the foam making the poly matrix sticky and retain dirt. Foam filters do not block dirt, they grab it all while making minimal drops in air flow. What does this mean to you? More dirt collected, more air flow and more horsepower.

Cleaning is simple. Just spray on your oil filter cleaner, let it sit on the filter element for a few moments, and simply rinse away the cleaner and dirt. Once your filter is dry, spray on a fresh coat of oil and you are ready to go.
