Karbonius E46 M3 CSL (S54) Carbon Airbox - Race
$2,249.00
The Karbonius E46 M3 CSL (S54) Carbon Airbox - Race is a track-focused evolution of the legendary CSL airbox, featuring an integrated snorkel that ducts cool air directly from the front of the car. The result is lower intake temperatures, improved airflow, and an even more dramatic induction note — all wrapped in a motorsport-grade carbon fiber package.
Manufactured from 100% prepreg carbon fiber and autoclave-cured in Spain under strict ISO 9001 quality standards, the Race Airbox is produced by highly qualified staff through a manual process with exhaustive quality control at every stage. The UV-protective clear coat is available in gloss or matte over a 2x2 twill or 1x1 plain weave, for a stunning appearance that holds up in any environment.
Beyond measurable horsepower gains, the Race Airbox delivers sharper throttle response and that unmistakable S54 CSL induction roar — now with built-in cold-air ducting that eliminates the need for a separate snorkel.
