there is a plug socket in the toolkit that comes with the bike, use it with one of the other wrenches in the toolkit and the plugs are easy to remove!It's a pain in the butt (at least for me, maybe there is a trick).
Remove the gas tank and airbox off the throttle bodies. I know there are videos for that, I can't remember if any of mine show that or not in my Power Commander install video. After that, use a combination of small extensions and swivel bits to get the plugs out.
Me (and other people) have unfortunately found iridium plugs to screw things up. It's harder to find, but get the original NGK non-iridium plugs.
