Solution

1. Preparation

Gather tools and parts needed for the replacement.
Tools Required: Socket set (including 10mm and 14mm sockets), torque wrench, spark plug socket, ratchet, feeler gauge, dielectric grease, shop towels.
Safety Warnings: Ensure the engine is cool before beginning the replacement process.

2. Remove Engine Cover

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical shorts.
2. Remove any screws or clips holding the engine cover in place using the appropriate socket or screwdriver.
3. Gently lift the engine cover off and set it aside.

3. Remove Old Spark Plugs

Sub-steps:
1. Locate the spark plug wires or ignition coils and carefully disconnect them.
2. Use a socket wrench with a spark plug socket to carefully unscrew the old spark plugs. Turn counterclockwise until they are free.
3. Inspect each spark plug for wear and deposits, and clean the area around the spark plug holes to prevent debris from entering the combustion chamber.

4. Install New Spark Plugs

Sub-steps:
1. Check the gap on each new spark plug with a feeler gauge and adjust if necessary according to the manufacturer’s specifications.
2. Apply a small amount of anti-seize lubricant to the threads of each spark plug to facilitate future removal.
3. Carefully insert each spark plug into its respective hole and hand-tighten to avoid cross-threading.
4. Use a torque wrench to tighten the spark plugs to the manufacturer's specified torque (typically around 13-15 lb-ft).

5. Reassemble Components

Sub-steps:
1. Reconnect the ignition coils or spark plug wires, ensuring they are seated properly.
2. Reinstall the engine cover and secure it with screws or clips.
3. Reconnect the negative battery terminal.
