Momentums unique filter-to-housing interface was built to feature the largest air filter possible. These 8 tall 360-degree radial flow air filters feature a 3" flange and our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Their 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. Their expanded metal provides impact protection. These one-piece sealed housings, constructed of heat-resistant XLPE (cross-linked polyethylene) polymer, feature our patent-pending filter-to-housing interface. Their innovative design minimizes the total number of parts, making for an easy installation. Two clear sight windows allow for hassle-free filter inspection, without having to disassemble your system. This system features high quality, computer-designed, dyno-tuned intake tubes to achieve maximum power gains while maintaining a perfect fit. Their XLPE material is heat soak resistant and extremely durable. High quality premium clamps and silicone bellow couplings 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.
