Hell, I do all 6 with nothing but a 3" extension. Takes me about 15 minutes (not including gapping).
BTW, the reverse numbering for the NGK plugs may only apply to the V-power. With those, a higher number is colder.
Copper plugs are recommended for forced induction. I know platinum is a problem, not sure about the Irridiums.

Can you tell I haven't had to do them yet??
Once you get the factory wires off, plug changes are simple. I can do a plug change in 15 minutes or less on the GTP, including gapping and everything, and like will said, all I need is a ratchet, 3" extention, and socket...it would be quicker but its a bad idea to use the air ratchet on spark plugs.
As long as you get the RIGHT plug, you can run platinum plugs in supercharged engines, and honestly that is what I would recommend anyone put in who doesn't want to do plug changes twice or more a year. We ran platinum plugs in the GTP up until mid October when we switched to coppers as an experiment, and haven't switched back because they performed just as well (but not noticably better or worse). We have always and probably will always run platinums in the SSEi too, and we haven't had any problems with it not running well. Since the cars come with platinum plugs from the factory you can pretty much guess that it isn't going to hurt them to run platinum plugs.

i think that iridium and platinum are not recommended for SC, right? They burn the metal off or something?
