2. Remove Components

Sub-steps:
1. If present, remove the engine cover by unscrewing the bolts (typically 10mm).
2. Disconnect the ignition coil connectors by pressing down on the tab and pulling them off.
3. Remove the ignition coil bolts (typically 10mm) and gently pull the coils out of the spark plug wells.

3. Remove Old Spark Plugs

Sub-steps:
1. Use the spark plug socket with an extension to unscrew the old spark plugs counterclockwise.
2. Carefully lift out the old spark plugs from their wells, inspecting them for wear or damage.

4. Install New Spark Plugs

Sub-steps:
1. Apply a small amount of anti-seize compound to the threads of the new spark plugs (optional).
2. Hand-tighten the new spark plugs into the wells to prevent cross-threading.
3. Use a torque wrench to tighten the new spark plugs to the manufacturer’s specified torque (usually around 13 lb-ft or 18 Nm).

5. Reinstall Components

Sub-steps:
1. Reinstall the ignition coils by pushing them down into their respective wells until they click in place.
2. Secure the ignition coils with their bolts.
3. Reconnect the ignition coil connectors.
4. If removed, reinstall the engine cover and secure it with bolts.
