cold air does not necessarily more efficient... it means more dense air that the computer compensates for with more fuel. So you're looking at greater fuel consumption. Assuming the CAI gives more power, then of course you use more fuel to achieve more power.

So, warmer air = leaned out fuel input = reduced power. There are additional ways in which the WAI can benefit fuel efficiency, including apparently more complete burn thanks to increased engine temp.

The info's out there. Look it up.

Haven't you noticed how cars get terrible mileage in the winter? Same reason.

Most of the terrible mileage in winter is due to how much longer it takes a car to warm up and reach closed loop operation.

Winter blends of gas (ie, oxygenated) kills MPG more than any other factor.

The more you curse, the worse it gets

Proof?

Do you have any idea how much more fuel an engine uses during open loop operation?
