This 7-1/2” tall 360-degree radial flow air filter features a 3-1/2” round flange and our oiled Black Pro 5R media with five layers of progressively finer cotton gauze media for maximum airflow and performance. This media is best suited for street and track use. The smooth one-piece sealed housing, constructed of heat-resistant orange XLPE (cross-linked polyethylene) polymer, features our patent-pending filter-to-housing interface. A clear sight window allows for hassle-free filter inspection, without having to disassemble your system. This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat-soak resistant and extremely durable. This intake is designed to use factory mounting locations, minimizing the use of unnecessary hardware, ensuring a perfect fit every time. Its revolutionary design, featuring our patent pending filter-to-housing interface uses half the number of parts of a traditional cold air intake system. Stainless-steel worm clamps are included for strength, and a premium bellows coupling allows for ample flexibility.
