Momentum*s unique filter-to-housing interface was built to feature the largest air filter possible. This 9* tall 360-degree radial flow air filter features our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street use. Its inverted top makes for more filter surface area, resulting in longer service intervals. This media is best suited for street and light off-road use. The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE), features our patent-pending filter-to-housing interface. Its innovative design minimizes the total number of parts, making for an easy installation. A large, clear sight window allows for hassle-free filter inspection, without having to disassemble your system. The housing incorporates the factory air inlet scoop. A silicone seal piece finishes the inlet of the housing and seals to the hood to block off unwanted hot engine air from entering the air intake 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. Stainless-steel clamps are included for strength, and premium silicone couplings allows for ample flexibility. Momentum GT intakes are designed with fewer parts for a fast and easy installation.
