Don’t let a flimsy paper filter get between you and true performance. The PERRIN Performance™ dual stage, “Open Cell” foam, drop-in Panel Filter is the answer. A stealthy approach to higher air flow. Increases in horsepower are a simple easy install away! Quick cleans are simple with our aerosol cleaner and spray oil. After all, more air equals more power!

Open Cell Foam Element

PERRIN foam filters are made of reticulated polyurethane foam which offers a minimal amount of air. 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 as they grab dirt! What does this mean to you? More dirt collected, more air flow and no clogs!
