Solution

1. Preparation

Gather Tools and Parts:
- Tools Required: Socket set, torque wrench, spark plug socket, extension bar, ratchet, anti-seize compound, dielectric grease.
- Parts Required: New spark plugs (specific to the engine type).

2. Disconnect Battery

Safety precaution: Disconnect the negative terminal of the battery to prevent any electrical short circuits.

3. Access the Spark Plugs

Remove Engine Cover:
- If equipped, unscrew or unclip the engine cover to gain access to the spark plugs.
Remove Ignition Coils:
- Disconnect the electrical connectors from the ignition coils.
- Remove the bolts securing the ignition coils and gently pull them out.

4. Remove Old Spark Plugs

Use a Spark Plug Socket:
- Insert the spark plug socket onto the first spark plug and turn counterclockwise to remove it.
- Repeat for all spark plugs in the engine.

5. Install New Spark Plugs

Apply Anti-Seize Compound:
- Lightly coat the threads of the new spark plugs with anti-seize compound to prevent seizing.
Insert New Spark Plugs:
- Hand-tighten each new spark plug into the cylinder head, then use the torque wrench to tighten to the manufacturer’s specified torque (typically around 20-25 Nm, but check specifications).

6. Reinstall Ignition Coils

Place Ignition Coils Back:
- Insert each ignition coil back into its respective position.
- Reattach the bolts and connect the electrical connectors securely.

7. Reattach Battery and Engine Cover

Reconnect Battery:
- Attach the negative terminal of the battery.
Replace Engine Cover:
