Maybe I didn't parse the sentence correctly then.
What I'm not getting is how numerous folks have increased their FE using warm air intakes (the theory being that thinner air causes the ECU to inject less fuel to maintain the correct AF ratio in all conditions, with a slight loss of HP at the top end), the OP claims cold air should increase FE by making a little more HP, but then turns around and says that his idle fuel consumption doesn't seem to be affected by air temp. (The last doesn't seem correct, assuming it's being measured accurately.)
So something doesn't add up.
