high-volume intake for the E46 M3 (CSL-like sound)

E46 M3 S54 Carbon Fiber Polycarbonate Intake (E36 M3 S54 swap compatible) Coffee this intake maximizes the amplificationUltra lightweight Carbon Fiber Infused high flow, high volume intake for the E46 M3 (CSL like sound) Utilizing a near exponential horn shape to transition from the MAF diameter to the 6" intake pod, this intake maximizes the amplification of engine sound while minimizing weight. Compared to a Borla exhaust, this setup is even louder from within the cabin! The OEM intake box while well designed, is very heavy, and significantly silences the awesome
