ahahaha, yea aem is full of crap so is DC sports
the intake will make your car sound cool
the non-vtec h23a1 Si prelude will see almost no HP gains and lose some TQ numbers
the VTEC h22a1/h22a prelude will see a few extra HP from the AEM short pipe and very unpredictable gains from a CAI...both will cause the motor to lose TQ.
The best intake IMO is the stock intake pipe and box with resonator removed and the K+N drop in filter...i beat a VR6 GTI with the stock airbox and lost to the same car by a car length with my AEM do the math our torque-less wonders need all the help they can get
