Perrin Drop-In Filter WRX / STI (2008-2018) LGT (2005-2009)

Product Description

The Perrin drop-in air filter for the Subaru WRX/STI/Legacy GT 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 filter can be cleaned and re-oiled using the Perrin cleaning kit, sold separately.
