Does this really make a difference without the full stage one kit? I must admit that I fitted the G56 cover prior to also fitting the exhausts and noticed no real difference in performance. Adding the G56 exhausts transforms the drivability of the car but in my experience it was the exhausts that made the biggest difference.
Air flow capacity on the inlet presumably impacts performance more in when you are consuming more air ie at high revs. So probably useful on a race track, and probably more for looks on the roads... (said as one who changed the exhaust not the intake, so again I might be wrong!)...
