The Cobb SRI with the Cobb cold-air box (and stock snorkus) is the intake that acts closest to the stock intake (tune-wise) of any out there. It is the only non-stock one I will accept when loading an off-the-shelf Stage 2 map onto somebody's car (besides the upcoming KSTech 65mm CAI's and 70mm LGT/08+ CAI's). Some people like the APS 65mm CAI but it always acted funny for me at part throttle and sometimes at idle.
The stock airbox is pretty restrictive. I measure about 40in.-H2O of pressure drop across at about 5 volts. There is some power to be had with a good intake, especially with tuning, but it is not a good mod (value-wise)for Stage 2 and below
How do I know this? I have installed and/or tuned and/or tested a couple dozen different intakes on my car and others'.
