aFe's high performance, high flow OE air filters replaces the restrictive factory paper filter and lets your engine breathe better. Paper filters do a good job in keeping dirt out but can clogged easily so that it needs to be replaced frequently. Foam filters also clog easily. A washable/reusable, cotton gauze filter like ours, allows more airflow and is washable and reusable. aFe's filters feature a pliable progressive polyurethane seal, the deepest pleats in the industry, minimal wicking, and are factor pre-oiled with non-surfactant containing refined oil.
