Follow the thick rubber wires that lead to the engine to find the spark plug locations.
Use your fingers to remove the wire from the spark plug on the end.
Check to see that the spark plug socket has a black material inside. If it does not, insert a small amount of tape in the socket.
Secure the socket to the ratchet, and then secure the extension to the socket. Place the ratchet over the spark plug, and remove it.
Insert the wire side of the spark plug into the socket, and place it inside the hole gently.
Tighten the spark plug by hand, and then use a torque wrench to tighten the spark plug to the proper specification found in your manual.
Slide the wire over the new spark plug, and ensure it's secure.
Repeat the steps to replace the remaining spark plugs one by one.
