Even at idle, air has virtually no appreciable time to absorb any heat that may be conducted through the aluminum pipes. If the tubes were made of plastic they would be the same temp. Heat up an oven to 300 degrees put 1 piece of aluminum and 1 piece of plastic in it. They will both heat up to the same temp. It's the same principle in your engine compartment.

Ambient air is heated anywhere from 30 deg to 70 degrees F between the atmosphere and the IAT sensor. Cruising at highway speeds lowers the temperatures, and sitting at a traffic light causes IAT to skyrocket, as much as 20 degrees in 10 seconds.
While you might base your statement on cfm/RPM, the highest correlation between temp gradient is actually throttle position, not RPM.
So at idle, the TPS is around 5%, and air hardly flows at all. That's why underhood temps, and thus short-ram intakes, hurt so much.

I think I need to go to school to be a mechanic, then go get a degree in physics, then on to the debate team. Then I will be able to keep up with some of the discussions on this board.
I went ahead today and purchased a Comptech cold air intake. I like the look of it. It does not allow extra luggage space as do the injen or aem but I like that too.
I will install it the day it gets here and be back to give my opinions. Till then, chow.

Based on intake air temp reading using a laptop and the OBD-2 connection, your claim is entirely wrong.
