aFe Power MagnumFLOW Pro DRY S Air Filter 4in F x 6in B x 4.75in T x 9in H - 21-40035

The aFe Power MagnumFLOW Pro DRY S air filter (MPN 21-40035) is a high-flow, conical performance filter engineered for maximum airflow and simplified maintenance. This oil-free filter uses three layers of progressively finer synthetic mesh media to achieve a 99.2% filtration efficiency rating, providing superior engine protection without the need for re-oiling after cleaning.

Constructed with a 100% polyurethane top and base, the filter is built to withstand engine bay heat and vibrations for a long service life. The design features tall, evenly spaced pleats that increase the surface area for a high dust-holding capacity, while the pliable polyurethane flange with integrated bumps ensures a leak-free seal over the life of the component. Maintenance is straightforward, as the synthetic media can be washed clean with simple soap and water.
