Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet, spark plug socket, extension bar, dielectric grease.
Ensure the engine is cool to avoid burns.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Remove Engine Cover (if applicable)

Locate the bolts securing the engine cover.
Use a socket wrench to remove the bolts.
Gently lift off the engine cover and set it aside.

3. Remove Spark Plug Wires/Ignition Coils

For spark plug wires: Grasp the boot of each wire and pull straight out to avoid damaging the wire.
For ignition coils: Unplug the electrical connector on each coil, then remove the bolts securing the coils using a socket wrench. Pull the coils straight up to remove them.

4. Remove Old Spark Plugs

Use a spark plug socket and ratchet to loosen and remove the old spark plugs by turning counter-clockwise.
Inspect the removed spark plugs for wear or damage.

5. Install New Spark Plugs

Apply a small amount of dielectric grease to the threads of the new spark plugs to prevent seizing.
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 (typically around 13 lb-ft for Honda).

6. Reinstall Ignition Coils/Spark Plug Wires

For ignition coils: Place each coil over its respective spark plug and secure it with bolts. Reconnect the electrical connectors.
For spark plug wires: Push each wire boot firmly onto the corresponding spark plug until it clicks into place.

7. Reinstall Engine Cover (if applicable)

Align the engine cover and secure it with the previously removed bolts.
Ensure all bolts are tightened to the manufacturer’s specifications.

8. Reconnect Battery

Reconnect the negative battery terminal and ensure it is secured.
