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. The smooth one-piece sealed housing, constructed of heat-resistant XLPE (cross-linked polyethylene) polymer, features our patent-pending filter-to-housing interface. 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 bellows coupling allows for ample flexibility. Momentum GT intakes are designed with fewer parts for a fast and easy installation.
