Solution

1. Preparation

Tools Required: Socket set, torque wrench, gap gauge, ratchet extension, dielectric grease, and compressed air (optional).
Parts Required: New spark plugs (OEM recommended), new spark plug gaskets (if applicable).
Ensure the engine is cool before starting the replacement process.

2. Remove Engine Cover

Use a socket to remove any bolts securing the engine cover.
Carefully lift off the cover and set it aside, ensuring not to damage any clips.

3. Access Spark Plugs

Disconnect the negative battery terminal to prevent electrical shorts.
Remove any components obstructing access to the spark plugs (e.g., air intake duct) using the appropriate tools.

4. Remove Old Spark Plugs

Using a socket and ratchet, carefully unscrew the old spark plugs from the cylinder head.
Use compressed air to clean any debris from the spark plug wells before removing the plugs to prevent contamination.

5. Inspect and Prepare New Spark Plugs

Check the gap on the new spark plugs using a gap gauge; it should match the manufacturer’s specifications.
Apply a small amount of dielectric grease to the threads of the new spark plugs to aid installation.

6. Install New Spark Plugs

Carefully thread in the new spark plugs by hand to avoid cross-threading.
Use a torque wrench to tighten the spark plugs to the manufacturer's specified torque (typically around 13 lb-ft).

7. Reassemble Components

Reinstall any components that were removed to access the spark plugs, ensuring all connections are secure.
Reattach the engine cover and tighten any bolts that were removed.
Reconnect the negative battery terminal.
