Colder air is denser, which means for each air/fuel charge in the
cylinder, you're getting more air for the same amount of fuel. Cold air
also combusts far better. So if you travel in cold air a lot, your
engine should run a bit more powerfully. On my old Tenere (in my
pre-enlightened, pre-@ days) I could get an extra 8 or 9 kmh out of it
during winter when the temperature was below zero.
Note: you can get chargecoolers for car engines which actually inject a
mist of water into the carburettors to cool down the charge going into
the cylinder for more power.

	Shouldn't it be vice versa???? Cold air contains more oxygen,
doesn't it?
	Therefore, it should run leaner, when it's cold.
