This 7* tall 360-degree radial flow air filter features a 6-1/8* x 4-1/8* oval 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 and light off-road use. 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. Multiple air inlets bring in cool air when under power. The lightweight tube is computer-designed to achieve maximum power gains while maintaining a perfect fit. Manufactured from 100% twill weave carbon fiber, it features zero fiberglass and is clear-coated for the highest quality construction. This intake is designed to use factory mounting locations, minimizing the use of unnecessary hardware, ensuring a perfect fit every time. Its revolutionary design, featuring our patent pending filter-to-housing interface uses half the number of parts of a traditional cold air intake system. Stainless-steel clamps are included for strength, and a premium bellows coupling allows for ample flexibility.
