What’s the best way to change a spark plug?
Clean the area around the plug wire and plug on each cylinder so that no dirt will fall into the cylinder opening. Now remove the wire from the spark plug on the first cylinder.

On an inline 6-cylinder, they are located on the top or side of the engine head. On V6 and V8-cylinder engines, plugs should be separated evenly on each side of the engine.
