Air Filters

  • Two filter media options to choose from (Pro 5R & Pro Dry S) to match your vehicle’s needs.
  • Increased surface area maximizes air flow and provides additional filter surface for increased protection and filter life.

This is the product line that started aFe Power. In the late 1990’s aFe Power, a.k.a. advanced FLOW engineering, Inc., was founded to provide the ultimate air filter available to the market. After almost 15 years in business, aFe Power has developed a complete line up of high quality OE replacement and Universal Clamp-On (UCO) air filters for the BMW market. First off, aFe Power offers two air filter medias to match your driving environment and overall needs. The Pro 5R air filter media is a 5-layer progressive cotton gauze media that provides maximum flow and a 98.6% filter efficiency rating. The Pro Dry S air filter media is a 3-layer progressive synthetic media that requires no oils to clean and has a 99.2% filter efficiency which provides maximum convenience. aFe air filters also use a unique rounded, deep pleat design for maximum surface area and increased air flow.
