aFe Power

aFe Power is a California-based performance parts company best known for its aftermarket air intake systems and replacement engine air filters. The company's product lines span several filter technologies — including oiled cotton gauze (Magnum FLOW Pro 5R), dry synthetic media (Magnum FLOW Pro DRY S), and high-flow cold air intake kits — targeting the performance enthusiast market across domestic and import vehicles.

The Pro DRY S line distinguishes itself from traditional oiled cotton gauze aftermarket filters by using dry synthetic filter media that requires no filter oil during cleaning or re-oiling after service. aFe markets this as eliminating the MAF sensor contamination risk associated with over-oiled cotton gauze filter types. The company offers a limited lifetime warranty on its reusable filter products.
