OK, so in a nut shell. Because the engine is small it will run more efficient on warmer air because the engine uses a lot of energy turning the cold oil over. On the other hand when it is warmed up it would run better on cold air induction because your pulling more air by volume due to it being more dense with oxygen and having to work harder to warm that air up to use it.

It's kind of like you body and cold water you body has to use energy to heat the water before it could use the water. So if you used water that was closer to your body temp it would get processed faster thus hydration you faster.
