N54 engine and N52 is TOTALLY DIFFERENT. do more research and you will find what i'm talking about. and any 335i owner with tune should exercise taking cowl off every so often anyways so it took me only 5~10 minutes to get to coil pack... one of mechanic was amazed how fast i was able to strip it off... lol
