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?

The extended tip can create thread issues because the plug thread gets covered in carbon and then digs out the threads in the head on the way out...
