alot of people will notice a little bit better mileage with a cold air intake, also some tuners have an economy mode that will get you a little better mileage also, the main thing with these two mods is to be able to keep your foot off the gas as the power gains will be a little higher and the cold air intakes make your truck sound amazing. There are also other minor and not so minor things you can do but the cost of them are pretty hi, some say you can also ad a bed cover to gain better mileage. Hopefully more people chime in with ideas also
If you ever need pricing on anything feel free to contact me i would be more than happy to help you.
