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
Completely false, read the link I posted, with analysis and dynos.


Backpressure is never good.
