That's probably true if you have your foot to the floor all the time because the CAI will draw more air, but under normal driving, the amount of air passing through the system should be about the same, it just has an easier time flowing, so the engine doesn't have to work as hard to draw the air in. I think... I have the AirAid CAI and the PowerAid TBS, and my gas mileage has increased!mavrickjr7882 said:
