Abstract: A device for reducing sound emitted by the air intake of a internal combustion engine is provided. The device includes a dampening chamber formed of a one piece construction by rotational molding. Included as part of this mold are two tubular pipe-like sections designating both an inlet and an outlet whereby air is directed into the engine through the inlet and sound emitted by the engine is dampened as it enters the outlet of the silencer. The inlet and outlet are each formed within a pocket constructed in the mold that assists in creating the flow path for air as it moves throughout the chamber. The arrangement of the inlet and outlet in relation to one another assists in defining the sound reduction capability of the instant design and construction.
