Perrin Drop-In Panel Filter WRX / STI (2002-2007)

Product Description

The Perrin drop-in air filter for the Subaru WRX & STI uses a 2-stage foam filtration element to improve airflow in your stock air box; providing improved power and airflow while removing harmful particles from the incoming air. Using a special oil coating, the foam filter catches dirt particles while allowing air to pass unimpeded through the high-flow foam. This WRX/STI 2002-2007 filter can be cleaned and re-oiled using the Perrin cleaning kit, sold separately.
