Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before starting work.

2. Remove Ignition Coils

Tools Required: Socket set, ratchet, extension.
Remove the bolts securing the ignition coils.
Gently pull the ignition coils out, taking care not to damage the connectors.

3. Remove Spark Plugs

Tools Required: Spark plug socket, torque wrench.
Use the spark plug socket to remove each spark plug by turning counterclockwise.
Take note of the condition of each spark plug.

4. Inspect and Clean

Inspect the spark plug threads and cylinder head for debris.
Clean the spark plug holes using compressed air to prevent contamination.

5. Install New Spark Plugs

Apply a small amount of anti-seize compound on the threads of the new spark plugs (if recommended).
Install each new spark plug by hand to avoid cross-threading, then tighten to the manufacturer's specified torque (typically about 13-16 lb-ft for Honda).
Reinstall the ignition coils, securing them with the bolts.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine to ensure it runs smoothly and check for any error codes.
