RE: Your Thoughts
Good old Champions are what the Hemi craves. I always had great luck with Bosch Platinums, especially in all four of the 4.0 I6 engines I had in my Wrangler and Grand Cherokees, that engine performs so much better and picks up an easy 2 mpg also. So I put them in the Hemi at 30k. SOB hated them, ran so bad I thought I screwed up putting them in or messed up a gap big time. Nope, just hates them. Made inquirees on forums and found others reported the same, not only from Bosch Platinums, but just about all the high priced "performance" plugs...

I just did mine today. Take off the airbox lid and Hemi hat. Put a blanket on the cross member where the hood latch is. Sit on that to get the rear 4 plugs on driver side. The others you can do from the front and passenger side standing on the ground, unless you are really short.
You will need a 10mm socket along with a spark plug socket, various extensions and a telescoping pen magnet.
.045 gap.
While you are at it clean your TB, this will require a 8mm socket and of course a TB/Carb cleaning solution.
