I know there a bit expensive but I like Iridium plugs. I run them in everything from my snowmobile to my Jeep. I'v got the same GC as you, alltime 4wd. She's got 271,000km. on her and still runs like a champ.
The good ol champion copper plus do the trick. They are cheap and work great. I'm a firm believer of oem all the way from all the problems we see from aftermarket junk at the shop.
