Here are some real numbers for those of you that are not gear heads and believe some of the hype on this and other threads on the site. There is a current show on SPEED called Sports Car Revolution. For some real numbers in cars like ours, they are upgrading an Acura RSX-S 210hp @7800rpm. They Dyno ran the car and the stock intake with a chip cost them 11hp. In order to get some of that back, They added a cool air intake made by PIT. Heres what the dyno showed 4HP and the hope that at 100mph the ram air/cool air would provide another 1 or 2. This is the MAXIMUM you can expect from a WELL researched WELL engineered system. One thing you cannot do (to add power) is hang the filters on the front end and hope they will pick up cool air instead of hot air (from the engine compartment where they sit). Information makes for informed choices.
