Solution

1. Preparation

Gather the following tools and components:
- Socket set (10mm and 12mm sockets)
- Torque wrench
- Spark plug socket
- Ratchet
- Feeler gauge
- Anti-seize lubricant
- New spark plugs (ensure they are the correct type for your engine)

2. Disconnect Battery

Use a 10mm socket to remove the negative battery terminal.
Ensure that the terminal is secured away from the battery post to prevent accidental reconnection.

3. Remove Engine Cover

Identify and remove any screws or bolts securing the engine cover using a socket wrench.
Lift the cover off carefully and set it aside.

4. Remove Old Spark Plugs

Locate the spark plug wires or ignition coils and carefully disconnect them.
Use the spark plug socket and ratchet to unscrew each spark plug from the cylinder head.
Inspect each spark plug for carbon buildup or wear.

5. Install New Spark Plugs

Apply a small amount of anti-seize lubricant to the threads of the new spark plugs.
Check the gap on each new spark plug using a feeler gauge and adjust if necessary.
Hand-tighten each spark plug into the cylinder head, then use the torque wrench to tighten them to the manufacturer’s specification (usually around 15-20 lb-ft, but confirm with the factory service manual).

6. Reconnect Ignition Coils/Wires

Reconnect the ignition coils or spark plug wires to their respective plugs.
Ensure that they are seated properly to avoid any misfires.

7. Reattach Engine Cover

Place the engine cover back onto the engine and secure it with the screws or bolts that were previously removed.

8. Reconnect Battery

Reattach the negative battery terminal using the 10mm socket.
