E30 S54 swap AIRBOX made 100% in prepreg carbon fiber in our facilities in Spain under ISO 9001 Management Quality System rules by qualified staff. The BMW M3 E46 CSL it´s one of the most famous and mythical cars in the world, and part of the success is due to the carbon airbox. This intake generates what is probably one of the best noises of any sports car. For that reason, a lot of BMW E30 users want to get the same noise in their E30´s S54 Swap. As the E46 CSL Airbox does not fit correctly on the E30 chassis with the S54 Engine, we did some modifications on our Airbox to get a perfect fitment on these swaps. The S54 E30 Airbox comes without the front inner canalization that usually brings fresh air from the front bumper, also the box it´s modified on the rear, near the servo unit to prevent friction in that area.
