There is no debate.
Most people don't understand how fundamentally different gas and diesel engines are.
Diesels need cool air (not bitterly cold air) for better milage, gas engines usually need warm or hot air for better milage.
Simple thermodynamics lays it all out for us.
Factory manuals spell it out for the no so thermodymanicly inclined, cummins has recommendations that their engines draw air from out side the engine enclosure in all but the coldest climates "for the best fuel economy and performance".
