Solution

1. Preparation

Gather tools: socket set (including 10mm and 14mm sockets), torque wrench, ratchet, spark plug gap tool, extension bar, and a spark plug socket.
Ensure the engine is cool to prevent burns and damage to components.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Access Spark Plugs

Remove any necessary components, such as the engine cover, by using the appropriate socket to unbolt them.
Carefully detach the ignition coil connectors from each spark plug by pressing the release tab and pulling them off.

3. Remove Old Spark Plugs

Use a spark plug socket and ratchet to loosen and remove each spark plug. Turn counter-clockwise until they are free.
Carefully pull out the old spark plugs, taking note of their condition.

4. Install New Spark Plugs

Check the gap on the new spark plugs using a spark plug gap tool; adjust to the manufacturer’s specifications (typically around 0.043 inches for Honda CR-V).
Carefully install the new spark plugs by hand to avoid cross-threading. Once they are snug, use the torque wrench to tighten them to the specified torque (typically 13 lb-ft).

5. Reassemble Components

Reattach the ignition coils and connect the connectors until you hear a click.
Reinstall any components removed earlier, such as the engine cover, using the appropriate torque specification.

6. Final Steps

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes, checking for any irregularities.
