This 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. 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. It features a Takeda design inspired by import vehicles. The included performance air filter is surrounded by an open-element XLPE (cross-linked polyethylene) polymer housing that minimizes warm engine air for maximum performance. Its open design allows for easy viewing of the air filter and delivers an aggressive Air Intake sound. It features an incorporated scoop to capture air from the front of the vehicle. Stainless-steel clamps and reinforced silicone couplings are included for strength and durability. Momentum intakes are designed with fewer parts for a fast and easy installation. Included billet aluminum fittings allows stock connections to transfer over seamlessly. To maximize the amount of air going to the this Air Intake System, Takeda Turbo Inlet 59-20002 is available. This Turbo Inlet will remove the air flow restriction of the factory turbo inlet, providing a smooth transition for the air from the Takeda Air Intake tube to the turbo.
