Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery (negative terminal) to avoid any electrical shorts.
Allow the engine to cool completely before starting work.

2. Remove Engine Cover

Tools Required: Socket set
Remove any screws or fasteners securing the engine cover.
Carefully lift off the engine cover and set it aside.

3. Access Spark Plugs

Tools Required: Socket wrench with extension
Identify the location of the spark plugs, which are typically located on the top of the engine.
Remove any components obstructing access to the spark plugs, such as ignition coils.

4. Remove Old Spark Plugs

Tools Required: Spark plug socket, ratchet
Carefully remove the ignition coil from each spark plug by pulling it straight out.
Insert the spark plug socket onto the spark plug and turn counterclockwise to loosen and remove each spark plug.

5. Install New Spark Plugs

Tools Required: Torque wrench
Before installing, compare the new spark plugs to ensure they match the specifications (heat range, gap size).
Apply a small amount of anti-seize lubricant on the threads of the new spark plugs (if recommended).
Hand-tighten the new spark plugs into place, then use a torque wrench to tighten to the manufacturer's specified torque (typically around 22 lb-ft, but confirm in specific service manual).

6. Reassemble Components

Reinstall the ignition coils onto the new spark plugs, ensuring they are seated properly.
Replace any components that were removed to access the spark plugs.
Reattach the engine cover and secure it with the screws or fasteners.

7. Reconnect Battery

Reconnect the negative terminal of the battery.
