- Torque wrench
- Ratchet extension
- Pliers (if needed)
Parts Required:
- New spark plugs (OEM recommended)

Keep track of the order of removal if multiple plugs are being replaced.

5. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs (optional).
Hand-tighten each new spark plug into the cylinder head.
Use the torque wrench to tighten each spark plug to the manufacturer’s specification (usually around 13-16 lb-ft).

6. Reassemble Engine Components

Reattach any components removed for access, ensuring all connectors are securely fastened.
Reinstall the engine cover if applicable.
Reconnect the negative battery terminal.
