Cars often have a temperature controlled flap that diverts the
incoming air via the radiator in order to warm it up.

Cold air is denser so you get more air per unit volume to support
combustion so they also fit intercoolers to cool the air before it
enters the engine.

On start up better warm, after the
engine is warm the colder the better.

Wrong (partly) again. I guess you've never experienced "carb" icing
then?

Lord Hall, the point is combustion. I doubt the penny will drop.
