ABSTRACT:
An air heater and blower system is incorporated into an air filter for an internal combustion engine carburetor and blows heated air into the filter and into the carburetor under control of a thermostat. The air filter has an opening and a deflector plate to deflect some of the heated air against the carburetor and bowl beneath the filter so as to accumulate heat around the carburetor under the filter casing thereby increasing the efficiency of the engine in cold weather or when the temperature drops below the setting of the thermostat.
