Solution

1. Preparation

Tools Required: Socket set, torque wrench, extension bar, spark plug gap gauge, dielectric grease, vacuum cleaner (optional).
Safety Warnings: Disconnect the battery before starting to prevent electrical shock.

2. Remove Engine Cover

Sub-steps:
1. Use a socket wrench to remove the bolts securing the engine cover.
2. Gently lift the engine cover off and set it aside.

3. Remove Old Spark Plugs

Sub-steps:
1. Use a socket wrench with the appropriate spark plug socket to loosen and remove each spark plug.
2. Carefully pull the ignition coil connector off each spark plug before removal.
3. Clean the spark plug area with a vacuum cleaner to prevent debris from entering the combustion chamber.

4. Install New Spark Plugs

Sub-steps:
1. Inspect the new spark plugs to ensure they are correct for your vehicle.
2. Measure and adjust the spark plug gap if necessary using a feeler gauge.
3. Apply a small amount of dielectric grease to the spark plug threads.
4. Hand-tighten each spark plug into the cylinder head, then use a torque wrench to tighten to manufacturer specifications (typically around 15-20 lb-ft).

5. Reinstall Ignition Coils and Engine Cover

Sub-steps:
1. Reconnect the ignition coil connectors onto each spark plug.
2. Replace the engine cover and secure it with the bolts removed earlier.
3. Reconnect the battery.
