To install a spark plug, remove the wire from the existing spark plug, and remove the plug with a spark plug socket. You need a spark plug socket with an extension, electrical or masking tape, and torque wrenches.
- Locate the spark plugs
Follow the thick rubber wires that lead to the engine to find the spark plug locations.
- Remove the wire
Use your fingers to remove the wire from the spark plug on the end.
- Prepare the socket
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.
- Remove the first spark plug
Secure the socket to the ratchet, and then secure the extension to the socket. Place the ratchet over the spark plug, and remove it.
- Install the new spark plug
Insert the wire side of the spark plug into the socket, and place it inside the hole gently.
- Secure the spark plug
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.
- Return the wire
Slide the wire over the new spark plug, and ensure it's secure.
- Replace the remaining spark plugs
Repeat the steps to replace the remaining spark plugs one by one.
