I still think on turbocharged engines the gains from a CAI are extremely minimal or non existent in comparison to an SF intake.... Ok let's say you have a 10 deg difference in IAT... Once that air passes through the turbo I would bet that difference is even less.... I have not found any data that proves this wrong or right, but for those that have dealt with compressing and releasing gases know how quick and powerful the temperature change is... This temp difference post turbo will have such a minimal impact on power output with how hot the air is to begin with... This is why IC's are your workhorse for cooling... Now once you get into the heavily modified area and are trying to squeeze everything you can out then this would make a difference but in reference to typical Stage 2+ cars the dif is negligible....

If this weren't the case then I bet Cobb would have made a CAI....
