This aFe Magnum FLOW OE-replacement performance air filter drops into the factory airbox and uses Pro DRY S (oil-free synthetic, 3-layer) for high airflow with excellent dust-holding capacity. Its rounded, evenly spaced pleats add usable surface area, and the 360° polyurethane frame seals without gaskets and holds its shape through repeated heat cycles. Washable and reusable.
