Fuel Saving Tips
Install a Cold Air Intake
If you live in a drier climate, install a cold air intake unit to save 1 to 3 miles per gallon. This replaces the OEM air box and air filter assembly. With a CAI, cooler air is drawn in from lower in the engine compartment, so the engine does not need as much gas as compared to when it sucks in hot air from under the hood. Many car makers offer these as OEM performance parts and if installed by a dealer, won't affect your warranty.
