The aFe MagnumFLOW Pro DRY S performance air filter (MPN 21-91065) delivers high-efficiency filtration with the convenience of an oil-free design. This conical filter features three layers of progressively finer synthetic media captured between a 100% polyurethane base and top for structural integrity. The tall, evenly spaced pleats maximize surface area, providing excellent dust-holding capacity and superior airflow for longer service intervals.

Built for durability and ease of use, the Pro DRY S media requires no specialized oils; it washes clean with simple soap and water. The pliable polyurethane flange is engineered with integrated bumps to ensure a tight, leak-free seal against the intake housing over the life of the filter.
