This 9 tall 360-degree radial flow air filter features a 5-1/2" flange and our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. It provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases. This media is perfect for street and/or track use. Its inverted top makes for more filter surface area, resulting in longer service intervals. 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 and delivers an aggressive Air Intake sound. It utilizes the vehicle's OE air inlet with no additional hardware. The built-in air intake scoop captures cold air directly from the top of the radiator support thanks to its huge opening. 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. The computer designed system utilizes factory mounting locations, minimizing the use of unnecessary hardware, and ensuring a perfect fit every time. Its innovative design makes for a hassle-free, direct bolt-on installation process that requires no cutting or drilling. Stainless-steel clamps are included for strength, and a premium silicone coupling allows for ample flexibility. Magnum Force intakes are designed with fewer parts for a fast and easy installation.
