I pulled a plug today. 9000 miles since I owned the car. Looked toasty tan with a rusty orange tip. Running a tad lean? Car came with pertronix installed and beru rev limited rotor. Current plugs are WRC77 Bosch Supers. Any recommendations?

Thinking about it, the 5s should be fine, especially with the gas we have today. For purposes of clarity, the tern "extended reach" or "extended tip" does NOT refer to the length of the threads, it refers to the tip configuration. The terms "hot" and "cold" refer to the heat transfer properties of the spark plug, NOT the temperature of the electrode. Beyond all that, the plugs should be changed around 6000 miles. The change in 1974 to a 10K mile interval was made to satisfy the US bureaucracy, and does NOT reflect any changes in the engines or the quality of the spark plugs. As far as the parts guy the "R" stands for "Radio", why am I not surprised? He works at a FLAPS, right? Probably couldn't get a job at McDonalds ..................................
