Hello all
I just purchased an 06 330i and attempted to replace stock air filter with k&n thinking it's quick job...however, there is one screw that I can't get to with my tools and it's at an impossible angle. I cant get the airfilter box seperated unless that screw is out
any suggestions??? Also, I saw the comment on the already existing 3 stage intake system the car has so going to a k&n won't make sense and waste????
