The aFe Magnum SHIELD foam pre-filter slips directly over compatible aFe POWER air filters (PN 81-10069 and 87-10069) to capture large debris before it reaches the main element. Made from 1/2" open-cell polyurethane foam, it's washable and reusable, increases dust-holding capacity, extends service intervals, and can be oiled for extra protection in dirty or off-road environments.
