This 8-1/2” tall 360-degree radial flow air filter features 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, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street 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.
