Hi, I need the spacer between this part (Engine Air Intake Resonator) and the throttle body. It’s like a flat donut about a half of an inch thick and round- which fits like a collar- between the throttle body and Resonator. It’s made of a high heat rubber or similar material. I’ve been told by the dealer that it’s part of the Resonator and they don’t have a separate part number for it. Please lmk if you have it as a separate part or if it’s included with another part or kit. Thanks very much. Brian
