Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet, spark plug socket, dielectric grease, compressed air (optional)
Gather the necessary replacement spark plugs.
Ensure the engine is cool and parked on a level surface.

2. Remove Engine Cover (if applicable)

Sub-steps:
1. Locate the engine cover (if equipped) and identify any fasteners (screws or clips).
2. Remove the fasteners using the appropriate socket or screwdriver.
3. Carefully lift off the engine cover and set it aside.

3. Access Spark Plugs

Sub-steps:
1. Identify the spark plug wires or ignition coils above the spark plugs.
2. If equipped with ignition coils, disconnect the electrical connectors by pressing the release tab and pulling them off.
3. Remove the ignition coils by unscrewing the bolts holding them in place, then gently pull them out.

4. Remove Old Spark Plugs

Sub-steps:
1. Use a spark plug socket and ratchet to turn the spark plugs counterclockwise and remove them from the cylinder head.
2. If necessary, use compressed air to clean any debris from around the spark plug holes before removal.

5. Install New Spark Plugs

Sub-steps:
1. Check the gap on the new spark plugs and adjust if necessary to meet manufacturer specifications (typically around 0.028-0.032 inches).
2. Apply a small amount of dielectric grease to the threads of the new spark plugs to aid installation.
3. Carefully thread the new spark plugs into the cylinder head by hand to avoid cross-threading.
4. Tighten the spark plugs to the manufacturer's specified torque (usually around 15-20 lb-ft).

6. Reinstall Ignition Coils and Engine Cover

Sub-steps:
1. Reinstall the ignition coils by aligning them with the spark plug and pushing down firmly until they click into place.
2. Secure the ignition coils with their bolts and reconnect the electrical connectors.
3. If applicable, place the engine cover back on and secure it with the fasteners.
