Re: Does a Cold Air Intake Improve Gas Mileage?
I don't see how an intake kit improves mileage.
1. The stock intake is already cold air, most of the kits are drawing in warmer air than the stock setup. Cold intake air will lead to better spark advance, which will lead to fuel savings.
2. Restriction: the throttle plate causes all the restriction, the intake will only cause restriction a WOT.
