Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent electrical shock.
Allow the engine to cool down completely.

Tools Required:

Socket set (including spark plug socket)
Torque wrench
Feeler gauge
Ratchet extension
Compressed air (optional for cleaning)

2. Remove Engine Cover (if applicable)

Locate and remove any screws or clips holding the engine cover in place.
Carefully lift off the engine cover and set it aside.

3. Remove Old Spark Plugs

Locate Spark Plugs: Identify the spark plug locations on the engine.
Disconnect Ignition Coils: Unplug the electrical connectors from the ignition coils.
Remove Ignition Coils: Unscrew the bolts securing the coils using the socket set, then gently pull the coils out.
Extract Spark Plugs: Use the spark plug socket and ratchet to unscrew each spark plug from the cylinder head. Take care not to drop debris into the cylinder.

4. Install New Spark Plugs

Inspect New Spark Plugs: Check the new spark plugs for proper gap using the feeler gauge; adjust if necessary according to manufacturer specifications.
Install Spark Plugs: Carefully thread each new spark plug into the cylinder head by hand to avoid cross-threading.
Torque Spark Plugs: Use the torque wrench to tighten each spark plug to the manufacturer's specified torque (usually around 20-30 Nm, but verify in the owner's manual).
Reinstall Ignition Coils: Place the ignition coils back into position and secure them with bolts. Reconnect the electrical connectors.

5. Reattach Engine Cover (if applicable)

Place the engine cover back onto the engine and secure it with screws or clips removed earlier.

6. Reconnect Battery

Reconnect the negative battery terminal securely.
