Solution

1. Preparation

Tools Required: Socket set, spark plug socket, torque wrench, extension bar, compressed air, and anti-seize lubricant.
Ensure the engine is cool before starting the replacement to prevent burns.
Disconnect the battery by removing the negative terminal to avoid any electrical short.

2. Remove Engine Cover (if applicable)

Use the socket set to remove any screws or bolts securing the engine cover.
Gently lift the cover off and set it aside, ensuring no connectors are left attached.

3. Remove Spark Plug Wires or Coil Packs

For vehicles with spark plug wires:
- Grasp the boot of the wire and twist gently to loosen before pulling straight out to avoid damage.
For vehicles with coil packs:
- Disconnect the electrical connector by pressing on the tab and pulling it off.
- Remove the bolts securing the coil pack using the socket set and lift it out.

4. Remove Old Spark Plugs

Use the spark plug socket and extension to carefully unscrew the old spark plugs from the cylinder head.
Use compressed air to blow out any debris from around the spark plug holes to prevent contamination.

5. Inspect and Prepare New Spark Plugs

Check the gap of the new spark plugs using a feeler gauge; adjust if necessary according to manufacturer specifications.
Apply a small amount of anti-seize lubricant to the threads of the new spark plugs to ensure proper installation and removal in the future.

6. Install New Spark Plugs

Carefully thread the new spark plugs into the cylinder head by hand to avoid cross-threading.
Use the torque wrench to tighten the spark plugs to the manufacturer's specified torque (typically around 25-30 Nm).

7. Reinstall Spark Plug Wires or Coil Packs

For spark plug wires: Firmly press each wire back onto its respective spark plug until you feel it click in place.
For coil packs: Position the coil pack over the spark plug and secure it with bolts. Reconnect the electrical connector until it clicks.

8. Reattach Engine Cover (if applicable)

Align the engine cover and secure it in place with the previously removed screws or bolts.

9. Reconnect Battery

Reattach the negative terminal of the battery and ensure it is tight.
