churr all this probs gets asked alot but is the diameter for my air intake for my 330i 2004 3.5”?? n not 3” right haha just double checking so dont get wrong one.
IIRC, the diameter at the throttle body is different from the diameter at the MAF sensor. I don't remember the diameter at the throttle body, but at the MAF it's about 3.5".
this was helpless
