Hi:
It's really to replace, but #8 is hard to get to. All you need to do is remove the one (I think 7mm or 8mm bolt holding the coil pack in. Once the bolt is out, disconnect the wiring plug to the pack and pull it out. It looks like it will hit the fuel rail, but it will come out. To replace it, just do the opposite.
NOTE: Over the years, I have found it a good idea to replace the plug too. Also, many times the coil pack isn't bad and all that needs to be replaced is the rubber boot that goes from the coil pack to the plug. Check for gray spots where there may have been an arc of power to the engine and not to the plug. If you find that, try replacing the boot rather than a 60 dollar coil.
Let me know if you have any questions. I'll be glad to help.
