This 9" 360-degree radial flow air filter features a 5" 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, yet creates a heat-blocking seal when the vehicle’s hood is closed. It utilizes the vehicles OE air inlet with no additional hardware. 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. This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps and hardware are included. Its revolutionary design, featuring our patent pending filter-to-housing interface, uses half the number of parts of a traditional cold air intake system.
