After opening the hood, remove the four screws from the ignition coils to take them out, disconnecting the connectors as well. Use the appropriate spark plug wrench to remove the spark plugs one by one from their housing.

Inspect all of them and replace any that are burned out or too old. However, the best practice is to replace all four spark plugs at the same time. Install the new spark plugs using the same wrench and reposition the ignition coils by reconnecting the connectors and screwing all the screws back in.
