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:StormNISMO, I could have swon I read here somewhere that the CAI actually use more gas, since the computer wil see more air coming in it will use more gas to reach the set level of each. I was thinking of getting a CAI to try and increase my MPG, I am also getting a Blackmax cover so I was hoping both of these would really help. Was the posting I read mistaken? If anyone can help me understand better so I can make a better descision please.
