I would actually think that this would both not help the heat situation and
make your motor run worse, not better.  By the former I mean that
difference it might make will be minimal.  By the latter I mean that warmer
air tends to absorb aersolized gasoline (such as that coming out of your
injectors or down in your carb) much more rapidly, efficiently and
completely, thus giving a more combustible air/fuel mix.

Of course, this is just slightly informed speculation on my part...
