Solution

1. Preparation

Tools Required: Socket set, torque wrench, spark plug socket, ratchet, extension bar, spark plug gap tool, dielectric grease.
Disconnect the negative battery terminal using a wrench to prevent electrical shorts during the replacement.

2. Accessing the Spark Plugs

Remove the engine cover by unscrewing the bolts securing it. Use a socket wrench for this task.
If necessary, disconnect any vacuum hoses or wiring harnesses that may obstruct access to the spark plugs.

3. Removing the Old Spark Plugs

Use a spark plug socket attached to an extension bar to reach the spark plugs. Turn counterclockwise to loosen and remove each spark plug.
Carefully inspect each spark plug for signs of wear, such as electrode erosion or carbon buildup.

4. Installing New Spark Plugs

Check the gap on the new spark plugs using a spark plug gap tool, ensuring it matches the manufacturer’s specifications (typically around 0.043 inches for Honda).
Apply a small amount of dielectric grease to the threads of each new spark plug to facilitate installation.
Install each new spark plug by hand to avoid cross-threading, then tighten with the spark plug socket. Use a torque wrench to tighten each plug to the manufacturer’s recommended torque specification (usually around 13 lb-ft).

5. Reassembly

Reconnect any vacuum hoses or wiring harnesses removed during the process.
Reinstall the engine cover and secure it with bolts.
Reconnect the negative battery terminal.
