Spark plugs location and removal instructions needed

Hello,

The spark plugs are located right on top of the engine. See attached picture circle in red.
You will have to remove those wires and coils then you will be able to access the spark plugs.
You will need a 16MM spark plug socket and a ratchet wrench with extension to reach the plugs.
