Abstract
A connection between an expansion chamber outlet and a rubber cuff that accommodates an inlet portion of a throttle body exhibits a dovetail connection between an expansion chamber wall and the rubber cuff such that the expansion chamber has a dovetail recession while the rubber cuff has a dovetail projection. The rubber cuff is insert molded around the expansion chamber outlet such that the joined interface between the rubber cuff and the expansion chamber is from the molding. The dovetail prevents separation due to air forces through the chamber and cuff. A cuff groove opposite the dovetail projection, on a cuff inside diameter, receives a protuberance of the throttle body inlet portion. A band clamp fits around the outside diameter of the cuff, adjacent the throttle body inlet protuberance, to prevent movement of the throttle body. The cuff has a projection(s) to also prevent slippage of the throttle body.
