With some ratchet extensions, a little patience, and some bloody knuckles, you can get that #6 plug...it really isn't THAT hard to get to, I've done quite a few and it's not impossible...a little challenging, but after a few times it gets easier. It takes a little time, and it helps to wait for the engine to cool, then put a foot on the bumper, and kind of lean into the engine bay over top of the engine to get better leverage.
