The only mild benefit is a slightly sharper throttle response due to a shorter inlet tract. Here is an example: Say you have an ambient air with a temp of 20deg. Your turbo compresses to this to 15psi. Now the temp of the 'charge' air (out of the turbo) is about 60deg! (this figure depends on heaps of things like turbine compressor maps and turbo efficiency). If you ran this 60deg air through a large intercooler with 20deg air flowing past it you could expect the charge air to drop to maybe 30deg. (depends alot on the intercooler, hence bigger = better) The 30deg air at 15psi is alot more dense than the 60deg air at 15psi. More dense air means you can put more fuel in with the increased amount of air and hence get more power. Also, with a cooler charge there is less chance of detonation (knocking/pinging/pinking/pre-ignition) so you can run more ignition advance and again get more power! Hope this helps clear things up! PS. in a NA car the lowest intake temp you can get is ambient. The problem is most people put their filters in their engine bay where the temp is much higher after the air has gone through the radiator, past the exhaust, over hot engine components etc. As you know if you open your bonnet after driving it can get pretty hot in there! So Cold Air Induction attempts to get air directly from outside the car where it is at ambient. Also why if you change the stock airbox (often it has some form of CAI) for a pod filter in the engine bay you can actually reduce power! [Report message to a moderator]
