Oh yeah, youtube has some good DIY videos on the subject.
Two more points:
1. When you get the coil/boot off the head, use compressed air to blow out an amazing amount of dirt. THEN loosen and add seafoam
2. DO NOT USE an air ratchet. Use your hands.
3. The point of all the above is to remove carbon build up from the plug. If the plug were new and clean, there would not be a problem. Carbon is what makes the plug jam up and then break at the crimp point. Therefore, DO NOT attempt to get the plugs out without due diligence to carbon removal.
