Momentums unique filter-to-housing interface was built to feature the largest air filter possible. This 9 tall, pre-oiled 360-degree radial flow air filter features our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance and filtration. Its inverted top and large surface area provide much longer life between maintenance intervals. This media is perfect for street 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. 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 silicone coupling allows for ample flexibility.
