Perrin FR-S / BRZ Panel Filter
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.
Open Cell Foam Element
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.
