Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench
  • New spark plug (check your owner's manual for the correct type)
  • Gap tool
  • Anti-seize compound (optional)

Steps to Change the Spark Plug

  1. Preparation: Ensure the engine is cool to prevent burns. Disconnect the spark plug wire by pulling on the boot, not the wire itself, to avoid damage.
  2. 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.
  3. Check the 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.
  4. Install the New Spark Plug: 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 engine by hand to avoid cross-threading. Once hand-tight, use the socket and wrench to snug it up, but do not over-tighten.
  5. Reconnect the Spark Plug Wire: Push the spark plug wire boot back onto the new spark plug until it clicks into place.
