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.
