Higher combustion temperature gives better efficiency.
Using a infrared digital thermometer the intake on my jeep sits around 197 degrees f, and I'm sure that transfers to the in going air quite a bit! Looking into it it seems that the colder the air intake is the more thermally efficient the vehicle is. A lot of the people I see getting the best fe live in places that are regularly in the teens to below zero, but they can't maintain engine temperature so they have to use a intake heater!! After dropping the intake to as low a temperature as possible you'll need to insulate the engine to retain as much heat as possible because it takes longer to heat up, dropping efficiency!!
