I beg to differ on it not mattering, if it didn't matter then companies wouldn't offer aftermarket intakes for turbo cars. The cooler the air the more dense the air is so the more you can suck or cram into the intercooler. It may make only a couple of whp on a na car having a cold air intake vs a ram air intake, but I was wondering how big of a difference it would make on a boosted car. When I get MSnS up and running I will put the filter on the turbo inlet and make a pull and log intake temps and then do it with the "cold air" on and log intake temps and see what the difference is.
