I've seen about a 5% improvement in FE from raising my truck's intake temperature 50 F above ambient.

More power means you can get up to speed faster with the same shift points.
5% is a good improvement, and worthwhile. I'm curious how much this mod helps with an already warm engine going down the highway - in other words, if you took the cold start out of the equation.
