Engines that are "conditioned" by getting all components warmed up (10 miles at
50 mph) will run more efficiently because:
-hot engine oil is less viscous
-warm transmission fluid/gear oil is less viscous
-the mating parts in a warm engine are closest to design tolerances and have less
wear
-the FI spray evaporates completely in a hot cylinder with more
efficient/complete burn
If you don't believe this try passing your state emission test on a cold engine.

Yes cold air is better (in a warm engine). Moist air is even better (in a warm
engine).
