Subaru WRX / STI 2002-2007 Cone Filter PERRIN Foam Type 3.125'' Inlet (PSP-INT-201,221,225,231,301)
PERRIN Performance Subaru WRX / STI 2002-2007 Cone Filter PERRIN Foam Type 3.125'' Inlet (PSP-INT-201,221,225,231,301)
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.
