replace spark plugs

not hard at all. There are for coils on top the valve cover, you must unplug and unbolt each one. The sparkplugs are down in the hole. You need a 5/8 plug socket, an extension, and a racket. Remove the plugs counterclockwise, and the new ones should have the plug gap checked before installing them. Bolt the coils back on,plug them in. Done.
