A lot if the posts are about simple change of air filter - not a cold box
as I have always had them as difefrent.
To me sports induction is getting more air in and if it is in the same place (as most filter systems are) its not a cold box.
A cold box is only any use when you are producing a lot of heat - normally turbo engines on high boost . It also works best with some sort of "ram" air intake to make sure the air is cool
And if you change the filter for the sound thats definately NOT a cold box .
Absolutely fine to do (if thats your thing ) but not a cold box.
In my experience you get better result's with a Na engine when installed properly.
With a turbocharged engine the temps will on go as low as the intercooler will let them.
To lower intake temps on a turbo you fit and IC spray or something as fitting a CAI will do just about nothing to a turbo engine in terms of intake temps.
That I can agree with, what I was trying to say was you'd get better results off an NA than you would a turbo charged motor due to the intercooler.I agree with you sleeper, the colder the air enters the turbo if the same amount of energy is used to heat it up, the cooler it will leave the turbo. I don't think it's AS important as in an N/A car (due to intercooling) but the more boost and power you are running the more important it becomes imo.
