ok i know a decent amount of mechanics as to know what does what and can improve on an engine, but i got into a debate at work on CAI's with this import guy saying that CAI do not in any way improve gas millage and actually reduce it. I disagree with him, only in the sence of maybe a 1 mile improvement, but my argument stands that it can improve (and of course how you drive the car). So i need some technical advice here and facts to back to this up, because i dont understand how it works. is it that if there is cold air the volume of air fills the piston chamber up faster or more then the gasoline? please explain someone
