Apparatus is provided for use in association with an internal combustion engine to generate heated moist air which is directed into the intake manifold or carburetor of the engine. The apparatus employs a water-holding vessel equipped with coils for the circulation of hot lubricant and coolant fluids from the engine. Air is sucked into the vessel by virtue of the vacuum of the intake manifold. The air is then broken into a bubbled stream by passage through an apertured horizontally disposed sparger tube.
