Solution

1. Preparation

Gather tools and parts needed:
- Tools: Socket set, torque wrench, spark plug socket, extension, ratchet, and dielectric grease.
- Parts: New spark plugs (check owner's manual for specified type).
Disconnect the negative battery terminal to avoid electrical shorts.

2. Access Spark Plugs

Remove any components obstructing access to the spark plugs, such as the engine cover or air intake assembly.
Label and disconnect the spark plug wires or ignition coils to ensure correct reinstallation.

3. Remove Old Spark Plugs

Use a spark plug socket and ratchet to carefully unscrew and remove the old spark plugs from the cylinder heads.
Inspect the old plugs for signs of wear or damage and note their condition.

4. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs (if recommended).
Hand-tighten the new spark plugs into the cylinder head, then use a torque wrench to tighten them to the manufacturer's specified torque (typically around 13-15 lb-ft).
Reconnect the spark plug wires or ignition coils, ensuring they are seated properly.

5. Reassemble Components

Reinstall any components removed for access, such as the engine cover or air intake assembly.
Reconnect the negative battery terminal.
