This is possibly one of the best airboxes available in the market. With a built-in snorkel, it facilitates the air ducting from the front of the car, getting a lower temperature in the intake system and facilitating an optimal air flow. In addition to a gain of power, the M3 CSL Carbon Race Airbox provides improved throttle response and that fantastic induction roar as well as a stunning appearance, with a high gloss finish and UV protection.
