CSL-Style Carbon Fiber Airbox

$ 2,095.00 $ 2,300.00

The finest CSL-Style airbox on the market, equaling or exceeding the OEM piece in quality and attention to detail, from Karbonius Composites. This is perhaps the most sought-after modification to transform the M3's underhood heart and soul. The savage induction roar produced by the airbox is truly a spine-tingling experience.

This airbox is laid in pre-preg carbon fiber, and cured in an autoclave for the ultimate in lightweight strength and quality of finish, and comes with a 5 year manufacturer warranty against defects.

This is the most current version of the airbox, out of the new CNC aluminum molds with carbon molded throttle body coupling throats, versus aluminum couplers as seen on the earlier version.

Please note, this is for the airbox assembly only. Filter, tune, and other accessories for installation and proper function are not included.
