make sure you use a magnetic spark plug socket..... as using a reg socket or one with a rubber boot may let the plug slip out and the plugs are about 4-6 inches down inside a small area.this is with the 3.6 engine and the 2.4 engine as well..... i would also cover up the 3 open areas in the middle of the engine with a rag just in case something doesn't slip or fall into the the holes not sure what they are but to be safe precaution and DONT forget the insulation pad like he did... i am sure its there for a reason.. BUT a good video
