Installation Notes and Tips
Verify the engine’s required plug specification before installation, including thread diameter, reach, seat type, and heat range. The plug is pre-gapped at 0.044, but the final gap should always be checked against the vehicle service specification before use. Inspect ignition wires, distributor components, and coil condition during spark plug service to help avoid repeat misfire concerns.
