Momentums unique filter-to-housing interface was built to feature the largest air filter possible. This 9 tall 360-degree radial flow air filter features a large (6-3/4" x 4-3/4") oval flange and 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 and light off-road use. Its inverted top makes for more filter surface area, resulting in longer service intervals. The smooth one-piece sealed housing, constructed of heat-resistant red cross-linked polyethylene (XLPE), features our 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 included Dynamic Air Scoop attaches to the auxiliary air inlet to provide additional air. 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. Momentum GT intakes are designed with fewer parts for a fast and easy installation. This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps, couplings, and hardware are included.
