You guys are making it sound really hard... haha.
You dont absoloutly need swivels, or anything... just the right sized deep socket for the plugs, the correct socket for the COPS and an extention for the ratchet.
As far as moving stuff out of the way on the drivers side there is one little vaccum line and an electical connector that you can unplug and move aside if its in your way... youll know just what one it is. It may also help to remove the PCV vaccum line.
The passenger side isnt hard, just remove the intake tube running to the throttle body. There is one sensor plug that you can disconnect, again youll see which one it is.
Other than that, the BIGGEST aid will be a telescoping magnet to fish the plug out, cause the plug wells are deep and you cant fit your fingers in there very well, lol.
Make sure you blow the wells out with some air before you pull the plug, alot of dirt can fall in when you pull the COP out...
