Installation Notes

Verify thread diameter, reach, seat type, and heat range before installation. Confirm the specified gap for your engine family, since some listed applications call for 0.030", 0.035", 0.040", or 0.045" depending on model and engine calibration. Use the vehicle service specification for final gap setting and torque, and inspect plug wires, distributor components, and ignition timing at the same time for best results.
