carbed car .. think a warm air intake will help?

Yes, it's there on a plane for carb icing - but they can also go to higher altitudes to get less dense air into the engine and less wind resistance (which is standard practice).

They also have a manual control that leans the mixture and some planes have variable speed props which would be equivalent to a continuously variable transmission (CVT). All of this allows you to operate the engine at max BSFC.

I have owned some cars that were very prone to carb icing which manifests itself as lowering tickover as mixture gets over rich and eventually as the carb fills with ice the engine stops.I found the worst conditions for this were a temp just above freezing and damp foggy weather.Perhaps it was my background in aviation that made me experiment with carb heat and mixture controls from within my older cars. I used to have a 282 mile round trip comute and constant adjustment of mixture etc saved a bit of gas and helped break the boredom.
