Select the year of your BMW M3:
The BMW E46 M3 CSL is one of the most famous and mythical cars in the world, and part of the success is due to its carbon airbox. The intake generates what is probably one of the best noises of any sports car. The Karbonius CSL Style Airbox weighs in at a scant 1.7kg. It is made with 100% prepreg carbon fiber and baked at 125?? in an autoclave at their facility in Spain under ISO 9001 Management Quality System rules by qualified staff. It is recognized as probably the best CSL style carbon airbox on the market.
The Karbonius CSL style airbox is based on 3D scans of a genuine OE CSL airbox, but presents several differences from the original:
Depending on other modifications and tune, expected gains are up to 25hp plus improved throttle response and a fantastic induction roar.

The Karbonius CSL style airbox is based on 3D scans of a genuine OE CSL airbox, but presents several differences from the original:
- Trumpets made in carbon fiber instead in plastic: Resulting in additional weight reduction.
- Diameter and shape of the trumpets have been modified: Our larger diameter 51.5mm (vs 50mm) trumpets with a modified shape contribute to better airflow inside the engine.
- Exclusive 6th trumpet design: The standard 6th trumpet gets less air, so the shape has been redesigned to increase airflow.
- Softened internal chamber shape with sanding and clearcoat: Works to minimize the air turbulence inside the airbox.
Depending on other modifications and tune, expected gains are up to 25hp plus improved throttle response and a fantastic induction roar.
