  2. Remove the Spark Plug Cap: Gently pull the spark plug cap off the plug. Be careful not to damage the wire.
  3. Remove the Old Spark Plug: Use the spark plug socket and ratchet wrench to unscrew the old spark plug. Turn counterclockwise to remove it.
  4. Check the Gap on the New Spark Plug: Use a gap tool to ensure the new spark plug is set to the correct gap as specified in your owner's manual.
  5. Apply Anti-Seize Compound: Lightly coat the threads of the new spark plug with anti-seize compound to prevent it from sticking in the future.
