aFe Magnum FLOW Pro DRY S air filters are available for a wide range of vehicles. They feature three layers of oil-free synthetic media, making them a very easy-to-maintain performance air filter. With a progressive bump seal design and polyurethane frame, they're also extremely durable and simple to install. * Washable and reusable for multiple cleaning cycles: Pro DRY S filter media features three layers of progressive synthetic (Dry) media for maximum convenience. Deep, open pleats allow for increased surface area, flow, and dust holding capacity. * Pro DRY S filter media: This media is best suited for street use. Pro DRY S filters are easily recharged with aFe's Power Cleaner. * Rounded deep open pleats: aFe Power performance air filters use a rounded, evenly spaced pleat design which allows for more usable filter surface area, providing increased flow and greater dust holding capacity. * Progressive bump seal: This pliable sealing surface conforms to even the most uneven filter housing, making for a perfect filter fit and sealing surface every time. This design eliminates the use of gaskets or sealants and always goes back to its original form. * Full polyurethane frame: All aFe Power flat panel performance air filters are constructed with a full 360-degree polyurethane frame. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape.
