Product Description

The aFe POWER 21-91130 is a universal 5-inch clamp-on conical air filter featuring aFe's Pro DRY S oil-free synthetic media. With three layers of progressively finer synthetic mesh between a 100% polyurethane base and inverted top, it delivers strong airflow at 99.2% filtration efficiency - all without requiring any oil. Maintenance is as simple as a wash with soap and water, making it one of the most convenient high-performance filter options available for Magnum FORCE-style intake systems.

The compact 3-1/2 inch height and inverted top design maximize usable filter surface area despite the short profile, while the pliable polyurethane flange with integrated bump seal conforms to the intake housing for a consistent, leak-free seal without gaskets. The full 360-degree urethane frame provides structural integrity through repeated heat cycles. Best suited for street and light off-road use in any custom or aftermarket intake application with a compatible 5-inch inlet.
