Solution

1. Preparation

Tools Required: Socket set (10mm and 12mm), torque wrench, spark plug socket, extension bar, ratchet, compressed air (optional), dielectric grease.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Ensure the engine is cool to avoid burns.

2. Remove Engine Cover

Use a socket wrench to remove the screws or bolts securing the engine cover.
Carefully lift the engine cover off and set it aside.

3. Access Spark Plugs

Locate the ignition coils on top of the engine.
Disconnect the electrical connectors from each ignition coil by pressing the release tab and pulling them straight off.
Remove the bolts holding the ignition coils using a 10mm socket and ratchet.
Gently pull the ignition coils out from the spark plug wells.

4. Remove Old Spark Plugs

Use a spark plug socket and ratchet to carefully unscrew each spark plug from the cylinder head.
If necessary, blow compressed air into the spark plug wells to remove any debris before removing the spark plugs.

5. Install New Spark Plugs

Check the gap on the new spark plugs and adjust if necessary according to the manufacturer’s specifications.
Apply a small amount of dielectric grease to the threads of the new spark plugs to prevent galling.
Carefully thread the new spark plugs into their respective holes by hand to avoid cross-threading. Then, use a torque wrench to tighten them to the manufacturer's recommended torque (typically around 13 lb-ft or 17.5 Nm).

6. Reinstall Ignition Coils

Reinsert the ignition coils into their respective spark plug wells.
Secure the ignition coils with the bolts and reconnect the electrical connectors until you hear a click.

7. Reattach Engine Cover

Position the engine cover back on the engine and secure it with the screws or bolts removed earlier.

8. Reconnect Battery

Reconnect the negative terminal of the battery.
