Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the battery negative terminal to prevent electrical shorts.

2. Remove Engine Cover (if applicable)

Use a socket set to remove any bolts securing the engine cover.
Carefully lift off the engine cover and set it aside.

3. Remove Old Spark Plugs

Locate the spark plug wires or ignition coils.
Disconnect the ignition coils or spark plug wires from each spark plug.
Use a spark plug socket and ratchet to carefully unscrew and remove the old spark plugs.

4. Inspect and Prepare New Spark Plugs

Check the gap on the new spark plugs with a gap gauge; adjust if necessary based on specifications (typically 0.044 inches for Honda).
Apply a small amount of anti-seize compound to the threads of the new spark plugs (if required).

5. Install New Spark Plugs

Carefully thread the new spark plugs into the cylinder head by hand to avoid cross-threading.
Use a torque wrench to tighten the spark plugs to the manufacturer’s specified torque (usually around 13 lb-ft).
Reconnect the ignition coils or spark plug wires to the new spark plugs.

6. Reattach Engine Cover

Place the engine cover back on and secure it with bolts.
Reconnect the battery negative terminal.
