FYI, I wouldn't expect too much from a cold air intake.
Today I made note of the intake air temperature with the ScanGauge while out driving in a fully warmed car.
Ambient air temp: 34F
Air intake temp: 37F
That is a very small increase in temperature. Much less than I've seen in my smart Fortwo or Scion xA. I'd be surprised if a CAI will lower anything other than the balance in your wallet. But, I'm open to the evidence. I'm happy with the amount of power it has right now.
