Cold air is goin to help the turbo and blower guys more because it sees more dense air BEFORE compression, and the compression will be easier on the turbo, ie, faster boost, more boost... and the outlet temps will be colder than normal so the intercooler doesnt have to work as hard, and your engine is seeing overheated crap air....

A n/a car sees air that is different just from the ambient temp change, while the turbo will see MORE temp loss after the compression since before was colder to begin with...


And if cold weather leans you out, Im sorry your a retard, tahts why they made this gadget called a afpr, but I forget what zilvia.net called them, I like fprr...
