Dyno - Tuned Carbon Fiber Intake Tube A lightweight high - gloss twill weave carbon fiber tube directs filtered air from the air filter to the engine and eliminates the factory sound chamber. It's computer designed and tested to increase air flow, while also reducing weight and enhancing the visual appearance of the engine bay. It features a billet aluminum fitting for the OE vent hose and a built - in resonance chamber to reduce unwanted air intake noise without eliminating its deep tone.
