Momentum*s innovative filter-to-housing interface was built to feature the largest air filter possible. This 7-1/2* tall 360-degree radial flow air filter features a 4" 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 a sealed XLPE (cross-linked polyethylene) polymer housing that minimizes warm engine air for maximum performance. Its innovative design minimizes the total number of parts, making for an easy installation. A large, clear sight window allows for hassle-free filter inspection, without having to disassemble your system. Its auxiliary air inlet can be used to bring in additional air from the engine compartment, or can be closed with an included plug. 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, couplings, 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.
