Did this today. Wasn't as bad as I thought. Took me 3 hours all and all, start to finish, and I've never done this before. I was mentally preparing for at least a 5 hour ordeal. Coils came out with no problems. I had a little trouble with the #8 (driver side) plug, but I did driver's side first, but then once I figured out the combination of extensions and flex joint that worked it was all a breeze. The 5/8" spark plug socket --> Flex joint (3/8") --> 3" extension (3/8") --> Flex joint (3/8"). Plug that into whatever wrech you're using and you're good to go. Of course you still gotta move some shit out of the way, as mentioned in the diy.

I have replaced 1-3, may skip #4, install 5-7 and save 4&8 till I gt the correct extension or tool

Im a newbie to the sight but I was looking to change my plugs after I started to feel it misfire. Couldn't have done cylinders 4 and 8 without your right up. Thanks a million!!
