I bought a 77 911 powered with a 1993 964 3.6 engine. This pictured air duct came with the car. It's about 4 inches in diameter and has what looks like a temp probe on the right side. Can someone tell me what the temp probe is for? I thought it may be an air temp probe which is supposed to be on the injection harness but I'm unable to locate a related plug.
