Solution

1. Preparation

Tools Required:
- Socket set (10mm and 12mm sockets)
- Torque wrench
- Spark plug socket (with rubber insert)
- Ratchet
- Extension bar
- Anti-seize compound (optional)
- Compressed air (optional)
Parts Required:
- New spark plugs (OEM recommended)

Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather all tools and new spark plugs.

2. Remove Engine Cover

If applicable, remove the engine cover by unscrewing the retaining bolts with a socket wrench.
Carefully lift the cover off and set it aside.

3. Remove Old Spark Plugs

Locate the spark plug wires or ignition coils, depending on the engine configuration.
For ignition coils:
- Disconnect the electrical connector from each coil.
- Remove the retaining bolt with a socket and ratchet.
- Pull the coil straight out.
For spark plug wires:
- Gently twist and pull to disconnect each wire from the spark plug.
Use a spark plug socket and ratchet to unscrew the old spark plugs from the cylinder head.

4. Install New Spark Plugs

Inspect the new spark plugs for proper gap using a feeler gauge; adjust if necessary to manufacturer specifications.
Apply a small amount of anti-seize compound to the threads of the new spark plugs (optional).
Hand-tighten the new spark plugs into the cylinder head.
Use the torque wrench to tighten each spark plug to the specified torque (usually around 13 lb-ft, but check the manual for exact specifications).

5. Reassemble Components

If you removed ignition coils, reinstall them by inserting them back into place and securing them with the retaining bolts.
Reconnect the electrical connectors to the ignition coils.
If you removed spark plug wires, ensure they are firmly connected to the new spark plugs.
Reinstall the engine cover, securing it with the retaining bolts.

6. Final Steps

Reconnect the negative battery terminal.
Start the engine and check for smooth operation.
