Solution

1. Manufacturer Recommendation

Honda typically recommends replacing spark plugs every 60,000 to 100,000 miles for the Eleventh Generation Accord, depending on driving conditions and the type of spark plugs used.

2. Inspect Existing Spark Plugs

Remove spark plugs using a spark plug socket and ratchet.
Check for signs of wear, such as carbon buildup or oil contamination.
Measure the gap using a feeler gauge; it should match the specifications outlined in the owner's manual.

3. Replace Spark Plugs (if necessary)

Tools Required: Spark plug socket, ratchet, torque wrench, feeler gauge
Perform the following:
1. Preparation
  - Ensure the engine is cold to avoid burns.
  - Disconnect the battery to prevent electrical issues.
2. Remove Old Spark Plugs
  - Carefully unscrew the spark plugs using a spark plug socket.
  - Keep track of which plug came from which cylinder for reinstallation.
3. Inspect and Clean
  - Check the cylinder head for debris and clean if necessary.
  - Use compressed air to blow out any debris from the spark plug wells.
4. Install New Spark Plugs
  - Apply anti-seize compound on the threads of the new spark plugs (if recommended).
  - Insert the new spark plugs and hand-tighten them.
  - Use a torque wrench to tighten the plugs to the specification (usually around 13-15 lb-ft, check the manual).
5. Reconnect Everything
  - Reconnect the ignition coils and battery.

4. Final Quality Check

Start the engine to ensure it runs smoothly without misfires.
Listen for any abnormal sounds and check for warning lights on the dashboard.
