E46 M3 CSL Carbon Airbox - Karbonius

E46 M3 CSL Airbox made by Karbonius.

 

This is by far the best Carbon Fibre Airbox we have seen and dealt with in the past and the attention to detail is almost identical to the Genuine BMW AG E46 M3 CSL Airbox supplied by BMW, manufactured by Die Wethje.

 

These boxes are made from the finest quality Pre-preg carbon fibre 2 x 2 twill material which when completed makes these boxes ultra light and rigid.

After the moulding process is finished in the state of the art Aluminium mould the part is then left in the Autoclave and this process is the finishing touches to a truly superb piece.

 

The 'M Power' sticker which can be seen on the top of the Air collecter is supplied with the Airbox.
