Tools and Materials Needed
- Spark plug socket
- Ratchet wrench
- New spark plug (check your owner's manual for the correct type)

- Anti-seize compound
Steps to Change the Spark Plug
- Ensure Safety: Make sure the engine is cool to prevent burns. Disconnect the spark plug wire by pulling on the boot, not the wire itself, to avoid damage.
- Remove the Old Spark Plug: Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free.
- Check the Spark Plug Gap: Use the gap tool to measure the gap on the new spark plug. Adjust it to the specifications in your owner's manual if necessary.
- Apply Anti-Seize Compound: Lightly coat the threads of the new spark plug with anti-seize compound to prevent it from seizing in the engine.
- Install the New Spark Plug: Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket and wrench to snug it up. Do not over-tighten.
- Reconnect the Spark Plug Wire: Push the spark plug wire boot back onto the new spark plug until it clicks into place.
