Like the title says, when? Mine seems to run great but maybe I should get it done. I probably should have done it sooner ...hate to admit but I have 85,000 miles on original plugs.

The upper 8 plugs are due at 30,000 miles, I cannot remember the the miles for the lower 8 plugs but someone will find it I am sure. But my bet is at 85,000 you might as well do them all.
Ooops. OK. I'll do all 16. Seems like my dealer may have mentioned that. I service it at the same dealer all the time. Oh well, my bad.

Your deffinately a little over due for some new plugs. Maybe you'll even see an increase in gas mileage when you swap them out.

Well, I've done a good job of other maintenance, fluids and brakes. Time to get this handled. Color me red.

Just got back from getting new plugs. I had forgotten that I had them done at 50,000 miles, so not as bad as I thought.

You are describing the plugs in the 4.7L engine and not the Hemi that GP has. On the Hemi, all the plugs are on the top, side-by-side. In fact, there is a single coil pack per cylinder that has 2 boots coming out for the 2 plugs per cylinder. When I was changing my plugs, it was difficult to pull the coil packs off of 2 of the cylinders. On both of those, each coil pack left 1 boot in the cylinder head. It was a royal PITA to get them out! Make sure to use dielectric grease on the boots when reinstalling!Originally Posted by Knappster
BTW, I did my plugs at 30,000 and put in Autolite Iridiums. With conservative driving, I can get 19 - 21 mpg on the highway with gently rolling terrain.

Thank you, In time we will get a photo "how to" posted up on the forum. I only have 16,000 miles so I still have 3 or 4 years to go before I get to 30,000 miles
