Solution

1. Preparation

Gather tools and parts before starting the replacement process.
Tools Required: Socket set, spark plug socket, torque wrench, feeler gauge, ratchet, and extension.
Parts Required: New spark plugs (ensure they match OEM specifications).
Safety Warnings: Disconnect the battery before starting the work to prevent any electrical shorts.

2. Remove Engine Cover (if applicable)

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

3. Access Spark Plugs

Identify the spark plug locations on the engine.
If necessary, remove any components obstructing access, such as the intake manifold or air intake duct, following the manufacturer’s service manual.

4. Remove Old Spark Plugs

Using a spark plug socket, carefully unscrew each spark plug from its cylinder head.
Avoid dropping any debris into the cylinder when removing the spark plugs.
Inspect the removed spark plugs for wear and compare them with the new plugs.

5. Install New Spark Plugs

Adjust the gap on the new spark plugs using a feeler gauge to ensure they meet specifications.
Apply a small amount of anti-seize lubricant to the threads of the new spark plugs (if recommended).
Carefully thread the new spark plugs into the cylinder head by hand to prevent cross-threading.
Use a torque wrench to tighten the spark plugs to the manufacturer's specified torque (typically around 20 Nm, but verify with the service manual).

6. Reassemble Components

Reinstall any components that were removed for access, ensuring all connections are secure.
Reattach the engine cover and secure it with screws or clips.

7. Reconnect Battery

Reconnect the battery terminals and ensure they are tight.
