Evolve spent much time in ensuring their carbon airbox was produced by only the best motorsport development companies who are also responsible for producing F1 body panels. The aim was to produce the best aftermarket CSL style airbox ever released using up to date cutting edge manufacturing processes.
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.
The Evolve E46 M3 CSL Airbox is made of extreme high quality from 100% pre preg carbon consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards.

Great experience dealing with the team at SouthernBM. Sean in particular was fantastic with his knowledge, timely responses and ultimately work performed.
Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!
Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.
One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!
My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.
