Evolve has spent much time in ensuring our carbon airbox was produced by only the best motorsport development companies who are also responsible for producing F1 body panels.
Part of what makes the E46 M3 CSL special is the carbon airbox and it’s ability to produce what is probably one of the best noises of any sports car. An E46 M3 with a CSL airbox is probably the most ideal all round sports car for most enthusiasts giving far more power, throttle response and that fantastic induction roar. The advantages over any other modification are that no other gives as much power gain and the noise is not like that of an exhaust system. An exhaust system introduces additional noise at idle, part throttle and full load driving. An airbox upgrade makes no extra noise at idle, you can drive under partial load without hearing it. It’s only heard when you apply large amounts of load at engine speeds over 2500 rpm.
Until now not many tuning companies have been successful in fitting a good quality carbon airbox and making the engine run like a factory unit. There has always been a trade off in some way or another be it fuel economy, rough idle or poor performance. Evolve set out on a project with a goal of producing the best aftermarket CSL style airbox ever released using up to date cutting edge manufacturing processes.
At IND, we’re excited to officially offer this airbox for purchase to the community. It is an aesthetically beautiful piece, that also offers formidable power gains from the naturally aspirated S54 platform.
