BMW M3 - CSL Airbox Conversion Sound Check

This movie shows my BMW M3 before and after I have installed the original CSL Airbox including Alpha-N Software.
You can hear the (outside) sound improvement from before and after the conversion.
There is also a small performance increase by doing this modifications.
It's defently worth all the money, especially the sound is astonishing.

A video with inside car sound comparision will follow as well.

[jarrus464]

does the csl air box actually have an air filter in it?

[CodeZilla]

@jarrus464: Yes, of course.

[Victoriano3]

For what is the airbox made?

[CodeZilla]

Made out of carbon fiber.

For more power and better sound. (And look as well)

The sound of the M3 or M3 CSL is unique, not common like most cars..very cool sound between a V6 and a Sports Bike :P

[ccline84]

Pretty sure you have to have Alpha-N software like he has in his discription, which is a little over a grand.

Hi CodeZilla, Did you use a special re-map for the car after fitting the airbox?

[privateblue]
