Not sure how others did it, but the body shop said there's no way it'll fit if bolted to the oil cooler. I'll try to take some pics tonight and show you how it sits against the oil cooler.
That makes more sense. The oil cooler on the M3 is out further because of the flared wheel arches so the M3 duct would look like its inside if bolted to the cooler. I've been reading every thread I can find on it and I've seen the trimming that you need to do around the radiator shroud, etc. but some pictures would be hugely helpful if you could snap a few.
Does this duct cool the brakes as well or is that a separate duct?
