  2. Remove the Old Spark Plug: Use the spark plug socket and ratchet wrench to unscrew the old spark plug. Turn counterclockwise until it is free.

  4. Install the New Spark Plug: Carefully thread the new spark plug into the cylinder head by hand to avoid cross-threading. Once hand-tight, use the socket and wrench to snug it up. Do not over-tighten.
