Momentum’s innovative filter-to-housing interface was built to feature the largest air filter possible. This 7” tall 360-degree radial flow air filter features a 2-1/2" flange and our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. It provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases. This media is perfect for street and/or track use. Its inverted top makes for more filter surface area, resulting in longer service intervals, while its expanded metal provides impact protection. The one-piece sealed housing, constructed of heat-resistant XLPE (cross-linked polyethylene) polymer, features our patent-pending filter-to-housing interface. Its innovative design minimizes the total number of parts, making for an easy installation. A clear sight window allows for hassle-free filter inspection, without having to disassemble your system. This system uses a high performance reinforced silicone intake tube to achieve maximum power gains while maintaining a perfect fit. The air inlet duct is constructed from XLPE that is heat soak resistant and extremely durable. It is CAD designed for perfect fitment and connects to the housing with a silicone bellow coupling to accommodate engine movement. High quality premium clamps and a silicone bellow coupling are used for durability while also providing the most secure installation available. Momentum GT intakes are designed with fewer parts for a quick and simple installation.
