True true, I could hardly tell a difference as well and maybe im def but I couldn't really tell a difference in sound either. I suppose I need to freshen up my knowledge as well because I'm used to the older American cars (mustangs mostly) and I know there MAF's could easily get screwed up from to much oil on the filter but every tuner recommended an oiled one. Obviously the M3 is not a mustang
