That socket should help, might want an extension as well.

Before you put the plugs back, take note of the plugs condition as you take them out. I would take 8 paper cups and label them and drop the pulled plug in the tight cup, so you can easily identify any problem cylinders.

I like using anti sieze when putting back plugs, that makes it easier next change. Dielectic grease can be helpful protecting the cap, ot more pressie where the cap meets the top of the sparkplug. Keeps stray current down and keep water out. But, you don't want it on top of the plug, you put it on the side of the plug or rubber, but try not to get it on the small silver top.

Yes but I don't have a hemi so I do not have 16 top side spark plugs. I have 8 top/intake plugs and 8 bottom/exhaust plugs (at least that's how I have come to understand it). I'm pretty sure I read that the bottom exhaust side plugs were 100k change interval so I'm only changing the top 8 copper plugs. Please correct me if any of this is wrong.

edit: checked rock auto and the intake side plugs are (8) copper and the exhaust side plugs are (8) irridium

I have a very good mechanic but the shop he works at has a tendency to overprice easy jobs, case in point they wanted over $300 to change 8 spark plugs. So I have decided to attempt the job myself, I'm fairly confident turning a wrench so what the hell. I ordered 8 OE plugs and this nifty looking tool.

Any advice for this job? Any major do's or don'ts? Thanks in advance.

That socket might not fit,i had to grind down a plug socket to do the plugs on my old 13 that had a 4.7.The 4.7's are very tight around the plugs.it might be okay,just fore warning you,you might need to grind it down a bit.

found this on allpar.com

The 2008 redesign had two spark plugs per cylinder, a 9.8:1 compression ratio, better port flow, and new slant/squish heads.

If you see a real bad plug, good time to clean that cylinder.
