Folks "cold" air needs to be refridgerated air. Once your moving most of the hot engine air is flushed out, it's only stop and go driving where that is a real issue. The VOLUME and flow of that air is the area where a few CIA's excell over stock set ups. Just like the term "ram air" that Vararam likes to throw around. Ram air is produced by turbos and blowers not by a cold air intake. If you can accomplish 3 to 5 rearwheel horsepower and torque on a dyno you have done about the best you can hope for with a CIA. Are you gonna feel that.........NO. In your mind you will and the sound will change somewhat but realistically, no you can't feel that small of a change but you have a nice high flow filter and more volume for the intake and that is always a good thing.
