That sucks cause that would look really good on your e90. You know..they do make black duct tape. No one would ever know...
So question.. how does the air duct fasten or connect to the bumper?
Also I did a diagram comparison on the m3 and the 328 and the part #s didn't match up but the diagrams were identical. ...hmmm
