This 8-1/2* tall 360-degree radial flow air filter features 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. Its inverted top makes for more filter surface area, resulting in longer service intervals. The simple yet elegant one-piece sealed housing features our patent-pending filter-to-housing interface, making installation a snap. The housing is made out of lightweight, high gloss, clear-coated twill weave carbon fiber. A lightweight high gloss twill weave carbon fiber tube directs filtered air from the air filter to the engine. It's computer-designed and tested to increase air flow, while also reducing weight and enhancing the visual appearance of the engine bay. Premium stainless-steel T-bolt clamps and a reinforced silicone coupling are used for strength and durability. Designed with fewer parts, this system's installation is extremely simple and secure.
