M56 motors arent super performers anyway. If u want any noticable power get cams and a tune. Or a supercharger : ). Then get an exhaust.

I heard that even the air boxes/intakes on our BMWs are engineered so well that aftermarket intakes dont make a difference either. GO BMW
You are an flipping ****, and I'd appreciate it if you didn't post in this thread again.
