Large Three Layer Performance Air Filter: This 360-degree radial flow air filter features a 3.5" 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. Dyno-Tuned Intake Tube: 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. One-Piece Housing: The included massive 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, yet creates a heat-blocking seal when the vehicle's hood is closed. It™s design incorporates the OEM air scoop to ensure that it gets the coldest air available. Hassle-Free Installation: This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps, couplings, and hardware are included. Its revolutionary design, featuring our unique filter-to-housing interface, uses half the number of parts of a traditional cold air intake system. Included billet aluminum fittings allows stock connections to transfer over seamlessly.
