This 7” 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 use. This air filter was specially designed for the SRT Hellcat / SRT Demon / SRT Redeye. 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 massive air filter, yet seals to the hood to gather air from the factory hood scoop. The housing also connects to the factory headlight air inlet thanks to the scoop inlet provided. 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. All necessary clamps, a silicone bellows coupling, and all other hardware is included. For the SRT Hellcat and SRT Hellcat Redeye, the factory MUA (Multi-Air Unit Actuator) is easily connected to the air intake tube. All clamps and hose are provided to guarantee correct crankcase flow, avoiding check engine lights and damaging factory hoses and sensors.
