Momentum’s unique filter-to-housing interface was built to feature the largest air filter possible. This 8” tall 360-degree radial flow air filter features a 4" flange and our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. 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 use. Its inverted top makes for more filter surface area, resulting in longer service intervals, while reinforced metal provides maximum strength to prevent filter collapse. The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE), features our patented 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. The housing connects to the factory air inlet duct but also captures air from the opening in the fender to provide more immediate cool air to the engine. 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. To maximize the amount of air going to this air intake system, aFe POWER D.A.S. 50-70119S and D.A.S. XL 50-70119A are available and sold separately (Only Fits Toyota Tacoma). The Dynamic Air Scoop will replace the factory air inlet duct and provide more cold air to the air intake system directly from the front of the vehicle. Stainless-steel clamps and red silicone coupler are included for strength and durability. Momentum GT intakes are designed with fewer parts for a fast and easy installation.
