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.

A partition wall located within the water channel extends from the air conditioning case to the evaporator.
|Insert molding dial structure - A vehicle instrument cluster gauge may have a dial plate with an inner dial, an outer dial, indicia and graduations. The graduations may originate on a dial plate rear surface near or at the center of the gauge and traverse radially outward toward the outer or peripheral edge of the dial plate and wrap from the rear surface, around the peripheral edge and onto the front surface of the dial plate thereby creating a three-dimensional gauge structure with the dial plate. When on the dial surface, the front graduation part protrudes above and away from the outer dial face of the dial plate. The graduation may also create an overhang or cantilever by protruding over a front surface of the outer dial, and have edges formed by 90 degree surfaces and have a projected centerline directed radially through a geometric center of the dial plate, where a pointer may mount.
