Installation Notes and Tips

Verify thread diameter, reach, seat type, and heat range before installation. This plug uses a flat seat and 19.00 mm reach, so matching the engine specification is important for proper sealing and combustion chamber fit. Check the gap against the vehicle service information before installation, even though the plug is pre-gapped to 1.0 mm.
