The invention includes preferably a heater and associated filter located at the air intake side of the carburetor that is activated by circulating heated fluid contained within the engine cooling system. The heater, in preferred form, is conveniently sized and circular in configuration so as to encircle the filter positioned at the air intake side of the carburetor, however, a circular filter can be used to encircle the heater. The heater and filter are encompassed by a releasably securable cover to hold these components together and in place and to block the entry of dust, dirt or other invading elements.
