I'm sorry, but I'm going to have to disagree with everything you just posted Striker2237.

Intake pipe diameter and length definitely do play a role in the torque curve of the engine. Here is an article that shows some testing:

Also, its widely known that warm air reduces pumping losses and increases flame speed in the combustion chamber. Both of these things increase engine efficiency. Not all engines react well to warm air though due to a number of factors, but it mainly boils down to ignition timing. You get too hot and the ecu pulls timing and you loose some of the efficiency you gained from reducing the pumping losses. Each engine handles the warm air differently.
