Since the dyno is static, I doubt any dyno will show any significant gain for this intake, which shows true gains with incoming dense/cold air.

My take is this, if a Honda i-VTEC (Inegra R, '06 Civic Si, RSX-S) engines can gain 7~10 hp with just about any aftermarket intake, I believe our BMW motors, which has a valve timing/valve lift system that's more advance, will achieve similar if not more gains. The reason we don't feel s**t is because the torque curve is too flat and too smooth, it hides the sensation of acceleration.

All in all, I definitely enjoy the new growl, better throttle response...and the 3~5% horsepower gain of this intake.
