Use the spark plug socket wrench and ratchet to carefully remove the old spark plug. Turn counterclockwise until the plug is free. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.

3. Check and Gap the New Spark Plug

Before installing the new spark plug, use a gapping tool to ensure the gap is set to the manufacturer's specifications. This is crucial for proper ignition and performance.

4. Install the New Spark Plug

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully thread the plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug the plug, but do not over-tighten.
