- Torque wrench
- Spark plug socket
- Feeler gauge
- Ratchet
- Extension bar
Parts Required:
- Replacement spark plugs (check specifications)
Safety Warnings:

2. Remove Engine Cover

Remove any bolts or screws securing the engine cover using the appropriate socket.
Gently lift the cover off and set it aside.

3. Access Spark Plugs

Locate the spark plug wires or ignition coils on the engine.
Carefully unplug the ignition coil connectors by pressing the release tab and pulling straight out.

4. Remove Ignition Coils

Unscrew the bolts (typically 10mm) holding the ignition coils in place using the socket set.
Lift the ignition coils out of their respective spark plug wells.

5. Remove Old Spark Plugs

Using the spark plug socket, carefully unscrew each spark plug from the cylinder head. Turn counterclockwise until fully removed.
Take care not to drop debris into the cylinder head.

6. Install New Spark Plugs

Check and adjust the gap on the new spark plugs using a feeler gauge to match manufacturer specifications.
Apply a small amount of anti-seize compound to the threads of the new spark plugs (if specified by the manufacturer).
Install the new spark plugs by hand, turning clockwise until snug, then use a torque wrench to tighten them to the manufacturer’s specified torque (usually around 13 lb-ft or as specified).

7. Reinstall Ignition Coils

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

8. Replace Engine Cover

Position the engine cover back in place and secure it with bolts or screws.
