This 9” 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. Our Pro 5R media 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 and/or track 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 plain weave carbon fiber. A clear sight window allows for filter inspection without removal of the air box. On 2015 and up Challenger models, the housing can be connected to the SRT Hellcat-style headlight opening thanks to the Carbon Fiber Dynamic Air Scoop (sold separately: PN 54-72203-SF). A plug is provided for use if the auxiliary air inlet is not utilized. A lightweight high gloss plain weave carbon fiber tube directs filtered air from the air filter to the engine. Using 3D computer modeling, It's designed to increase airflow and provide a perfect fit. 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.
