Karbonius Carbon Fiber Airbox, S54 Swapped BMW E30

Karbonius 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 is one of the most famous and mythical cars in the world, and part of the success is due the carbon airbox. This intake generates what is probably one of the best noises in any sports car. For that reason a lot of BMW E30 drivers want to get the same noise in their E30's S54 Swap.

As the E46 CSL Airbox does not fit correctly on the E30 chasis with S54 Engine, we did some modifications to our Airbox to get a perfect fitment.

The S54 E30 Airbox comes without the front inner canalization that typically sucks in cold air. Additionally, the box is modified on the rear next to the servo unit to prevent friction in that area.
