1. remove all the plug wires and coil packs. ( be careful with the metal covers over the plugs if you end up having to use pliers )
2. LOTS of various size extensions, shortest being the 1" one, and at least 2 3" ones.
3. I cut a couple of lengths of tubing that fits tightly over the plug porcelin, makes it easy to remove them, and insures you don't cross thread upon installation.
4. bandaids and neosporin

5. DO THE PASSENGER SIDE REAR PLUG FIRST ! ( the rest will seem easy after that one )
