The air/fuel mixture would be minmized and the cold air wouldn't allow for the proper mixture (ever notice that you use more gas in the winter?). Warm dry air actually provides for a much better mixture of air/fuel giving you better accelleration. but yes driving in the snow rocks, only with RWD. sorry to get off topic.
The reason you use more gas in the winter is because your engine runs with a rich fuel to air ratio until it reaches operating temperature.

He probably right about the accleration thing, though it's unlikely it's enough horsepower difference to feel in the ass dyno.
Colder air will provide better power.
If you still don't believe me answer why people put cold air intakes on their vehicles to increase performance. Why do they add intercoolers?
