How do I go about a 100,000 mile tune-up, especially changing the back three spark plugs?

Upper intake manifold need to be removed
Depending on your engine size and how many valves

You don't need to take off the intake. Really it CAN be much simpler. Remove the pieces that attach to the Air filter area. This opens up a large space to work with, however, I will say you need patience, flexibility, good tools and skinny area. A cool engine never hurts either.
