So am I reading this correct the 2007 335is had the n54 than switched to the n55 than eventually went back to a newer n54 again?
I ask bc a good friend is looking at a used 2007 335is and he races a lot of autocross and I told him from what I remember the n54 was superior but I didn't realize the is went back to the n54??
