I figured I would do this as a little early maintenance. I didnt want o wait for the 105K or whatever nissan says to change them at. Since I was off for today and tomorrow, I figured might as well do this. I planned on it being a while, with removing the plenum and all, but to my very pleasant surprise, I was able to change the plugs out, WITHOUT removing the plenum. The only pesky part was the #1 coil wire. It's not long enough to be moved, it has to be unclipped, and its kinda cramped there to do so, but a little patience and it was good to go. The only tools I needed were a 3/8" ratchet, an 8" extension, 3" locking wobble extension, one universal joint and the 5/8" plug socket, and a 10mm socket to undo the coil bolts. All in all took 45 minutes, but 15 of that was trying to find a coil bolt that I dropped(which was hiding underneath the coolant bottle).
After removing all the plugs, they still looked to be in really good shape. I would say, 75K is probably a more wise time to wait to. I replaced them with the NGK Iridium IX, just because I get a good price on them and why not put the best in the truck. Heres the pics of the plugs:
