The Carbonio is great when compared to the US spec airbox. Since your car is a US spec, you will have power gains. Unfortunatley, it did change to a yellowish color, you can mildly see it in the photo. I'm going to paint it with matte black finish to improve the airflow. But yeah, you will feel the diffrence. If you want something better, get the renntech airbox. ITs proven to make more horsepower than the carbonio

sallam 3liekom.. This is moozy from usa n originally from Saudi Arabia. I got MErcedes cls63.. i seee ur car has the airbox carbon fiber. how is that working with u? did it change color at all n how many milage did u put on it?

I would appreciate any insight you may share about ECU tune vendors to stay away from. I have been considering a tune and Eurocharge comes to mind since I get down to Houston on a regular basis, but I certainly have my concerns.

Thanks
