This is a very simple project. First start with a cool engine, no sense burning yourself for this. Remove the 2 center bolts in the middle of the valve cover, they are 13mm and will come off easily. Now you can see your coil on plugs. Be sure to disconnect the plug attached to the coil on plug before you try to remove the coil. There is a clip that you push down on located on the connector and it should come off easily if you do it right. Do not force the issue. Take your time. Now the coil over plug should pull right out.
