Using the spark plug socket and ratchet wrench, carefully unscrew the old spark plug from the engine. Be cautious not to damage the threads in the cylinder head.

Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully thread the new spark plug into the cylinder head by hand to avoid cross-threading.
