Changing your plugs is pretty straight forward. All you need to do is take off the cover on the front and the back of the head. Next you will need to take off your throttle body so that you can get to the two center plugs. Next you will need the 5/8" plug socket (if you don't have one you can find them at any auto store) and a good 6" extension. Next just stick the extension and the socket in and loosen the plugs. Do the reverse for putting in the plugs. When you put the plugs back in you should tighten to hand tightness and not to tight. You can break the plug if you tighten them to much, trust I've done this several times. I'm going to be changing my plugs soon, so I guess I have a write-up to do. Thanks
