I tried their method of using a 1/2" swivel extension with no results. I couldn't get enough torque on the sucker to break it loose with tiny 1/4" ratchet that would fit back there. I tried using a 1/2" ratchet, but couldn't ever get the sucker in position and it was too big to work with back there. Right now my game plan is to go out there tommorrow and fiddle with the 1/2" ratchet and 1/2" extension and pray.
So how did you change your #8 plug? Can you get at the sucker better from underneath the car???(I doubt you could). How hard is it to remove that black plastic thing that is to the left and in the way?

When changing plugs, do yourself a favor and pull the coil packs for extra room. The #8 plug is easy to get from the top with a stubby ratchet. This way, you don't have to jack the car up and get it from underneath. Pulls the coil packs, and use a stubby. Problems will be solved.

I pulled the AIR tube and I slid the coil pack rail upwards, but didn't remove it(as specificed in the Install University instructions). I bought some more tools, including a really long 6" extension so I can get a big ratchet on that
b!atch and torque on it like no tommorrow. I think my problem was not having the right tools.

Forgot to mention all my plugs were stubborn and required significant amounts of muscle and knuckle bashing to break loose.

1. Put the socket on the plug first.
2. Place a short extention (1/2") on your wrench.
3. Use a short flex head wrench ($10 @ autozone)
If it is hard to get fill socket w/penitrating oil and cap it w/ your finger then put over the plug. Will smoke for a while when you start it up, but will help to loosen rusted in spark plugs.
good luck.

The key is to be in the proper position. Do yourself a favor and grab a milk crate and climb onto your battery. If you're kneeling on your battery, you'll have more control over the situation. That's how I did mine. Leaning over the fenders was killer on my back, and I couldn't get any leverage.

I put one knee on the battery and support my other foot with something so I can really see down there. As was stated, put socket on plug first then a 1/2" extension then rachet. Mine's a lot easier now that I relocated the coil packs and ripped out the AIR system and AC crap!!

Its mind over matter,course I can swap plugs in 25 minutes wihout breaking a sweat, But really if you go from the top,try this little tip,if you want to take the time remove the PS coil pack,but without doing that you can do it by,leaning over the front bumper and running your arm right above the manifolds/header tubes straight back toward number 8. I use a 3/8ths rachet/plug socket with a swivel/1 inch extension.After you do it once it will get easier each time. Good luck.

Well I finally got some time off of work this Sunday to change it. I removed the AIR tube of course. And then I completely removed the coil pack. That is the secret right there. I also tossed that back bolt into oblivion. 
I used a 3/8" to 1/2" adapter and then put my 1/2" ratchet on there.(on my previous attempt with the coil pack in place, I could only get my dinky 1/4" ratchet back there). I was on the battery the whole time BTW. I torqued on that sucker some, didn't get it loose. Got out the breaker bar and torqued some more. Finally it broke loose, and I didn't even bust my knuckles. I then ratched it out with the 1/2" ratchet until I realized that I couldn't get the ratchet out of there with the spark plug loose. The darn thing wedged itself into that little hole. So I tightened it back, got the 1/2" ratchet out, then got my 3/8" to 1/4" adapter. Got my little 1/4" ratchet in there and got it out. Tightened it back down with my 1/4" ratchet and torqued it down by feel.
I'd say the best tools for this job would be:
A 1" 3/8 extenstion.
A 3/8" ratchet with a small head and a long handle
A small 1/4 torque wrench so you don't have to do it by feel.

I take off the coil packs on both sides when doing my plugs. However, I still get number 8 from the bottom. I bought a 1" long extension for my 3/8" ratchet and that works really well on numbers 6 from the top and number 8 from the bottom.
