Designed to connect the air cleaner to the exhaust manifold to prevent carburetor icing in cold weather.

The Dayco emission control carburetor pre‐heater duct hose features a heavy-duty, flexible aluminum core and corrugated construction that can easily be cut with a sharp knife to facilitate the proper fit between air cleaner and exhaust manifold. The close inside diameter tolerance provides a tight fit to reduce carburetor icing.
