Installation Notes

Spark plug replacement on small engines is a common tune-up task performed by small engine technicians or qualified DIYers. Disconnect the spark plug wire before removing the old plug to prevent accidental starting. Use a spark plug socket and torque wrench when installing to avoid cross-threading or over-tightening the plug into the cylinder head. Consult the equipment manufacturer service manual for the correct plug gap specification before installation.
