Solution

1. Preparation

Tools Required: Socket set, torque wrench, spark plug socket, extension bar, ratchet, dielectric grease, and compressed air (optional).
Disconnect the negative terminal of the battery to prevent any electrical shorts.
Allow the engine to cool down completely to avoid burns.

2. Access the Spark Plugs

Remove any engine covers or components obstructing access to the spark plugs.
- Sub-steps:
  - Use the socket set to remove bolts securing the engine cover if applicable.
  - Carefully lift off the cover and set it aside.

3. Remove Old Spark Plugs

Disconnect the ignition coil or spark plug wire from each spark plug.
- Sub-steps:
  - Gently pull the ignition coil harness or wire straight out without twisting.
Use the spark plug socket and ratchet to carefully unscrew each spark plug.
- Sub-steps:
  - Turn counterclockwise to loosen and remove the spark plugs.
  - If there is debris around the spark plug, use compressed air to clean the area before removal.

4. Install New Spark Plugs

Apply a small amount of dielectric grease to the threads of the new spark plugs.
Hand-tighten the new spark plugs into the cylinder head, then use the torque wrench to tighten them to the manufacturer’s specification (typically around 13 lb-ft).
- Sub-steps:
  - Ensure the spark plug gap is set according to specifications before installation (usually around 0.043 inches for Honda).
  - Use the torque wrench to secure the plugs to prevent over-tightening.

5. Reassemble and Test

Reconnect the ignition coils or spark plug wires to each spark plug.
- Sub-steps:
  - Ensure a firm connection is made and that they are seated correctly.
Replace any engine covers or components removed during the process.
Reconnect the negative terminal of the battery.
