Currently, on my "S," I have the standard induction system with a K&N filter. The question is...is there that much of a difference between the standard system and the CAI? Will I feel that much of a difference if I change over? I already have CompTech Headers and Exhaust. Thanks for your opinion.

 

What do you mean by a standard system? A short ram intake with a filter at the end? If you mean that, then yes, a CAI or a box around that intake will lower the temps of the intake charge...colder air = denser air = more air molecules to mix with the fuel and cause a bigge bang = more power...the wonder of internal combustion.
