Man, Thanks for the help, Truely looks like a snap, I was thinking about using Bosch plugs and wires as an upgrade from the factory AC delco, any thoughts??

They didnt say anything about replacing the coil. They had me quoted at 3.5 hours labor just to replace plugs and wires. I dont think so!!!!

Why do you think Bosch would be an upgrade?

On the 07 up... All I have to add is Cylinder #7 is a bitch! So be prepared to take a few breaks in between and rest that back before you do this. I could see why it would cost 500 bucks. I'd charge way more for the S?*t one has to go through. The rest are easy breezy!

for a stock setup there will not be any extra benefit over the AC Delco product. I would not spend more money for another brand over the AC stuff - if you get them for less then I would consider that

If you are concerned about the quality or performance of the standard AC Delco spark plug that is in your Tahoe, know that its the exact same plug that is used in the 07 6.0L Corvette engine....

wound up using ac delco plugs and Bosch wires. No problems except # 8 was a bear to get to. cracked 1 plug first time around but finally got it.

wasnt really sure. I guess I bought into some hype. AC delco plugs are what I put in. Got Bosch wires for alittle less $.

very good - how many miles do you have and how did all of the original plugs look when you took them out?

Just about to hit the 100,ooo mark. The plugs didnt look as bad as I thought. alittle greyish in color and around the shaft some looked alittle burned. Not sure if I should have done the wires I didnt see any cracking on them, they looked pretty good. But it is what it is.DONE.
