Momentum*s 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. The housing incorporates the factory air inlet scoop. A silicone seal piece finishes the inlet of the housing and seals to the hood to block off unwanted hot engine air from entering the air intake 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. Stainless-steel clamps are included for strength, and premium silicone couplings allows for ample flexibility. Momentum GT intakes are designed with fewer parts for a fast and easy installation. Momentum GT Cold Air Intake System w/ Pro 5R Filter Ford F-150 21-23 V6-3.5L (tt) Ford F-150 21-23 V6-3.5L (tt)
