Solution

1. Preparation

Gather tools and materials needed for spark plug replacement.
Tools Required:
- Socket set (including a spark plug socket)
- Torque wrench
- Gap gauge
- Dielectric grease
Ensure the engine is cool before starting the replacement process.

2. Remove Engine Cover (if applicable)

If the Mustang has an engine cover, remove it by unscrewing any retaining bolts or clips.
Set the cover aside in a safe location.

3. Disconnect Ignition Coils

Unplug the electrical connectors from the ignition coils.
Remove the bolts securing the ignition coils using the socket set.
Carefully pull out the ignition coils from the spark plug wells.

4. Remove Old Spark Plugs

Use the spark plug socket and ratchet to carefully unscrew the old spark plugs.
Inspect the removed spark plugs for wear or deposits.

5. Install New Spark Plugs

Check the gap of the new spark plugs using the gap gauge; adjust if necessary.
Apply a small amount of dielectric grease to the threads of the spark plugs.
Carefully install the new spark plugs by hand to avoid cross-threading, then torque to the manufacturer's specification (typically around 13-15 lb-ft for Ford Mustang S550).

6. Reinstall Ignition Coils

Place the ignition coils back into their respective wells.
Secure them with bolts and reconnect the electrical connectors.

7. Reattach Engine Cover

If applicable, reinstall the engine cover by securing it with the bolts or clips.
