The Perrin drop-in air filter 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 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.
