How long did it take all of you to do them with the 4.7??
Yeah I used Autolite coppers and they worked fine and came pre gapped at .40. It took me about 40min on my Gen 1 4.7 (this was my first time doing it) I know the 07+ gen 2's used 16 plugs but if you have a Gen 1 it shouldnt take more then 45min. It was a really simple job especially if you have an aftermarket intake, I dindt have to remove or move anything with my K&N. I just undid the coil plug bolt, pulled the coil plug, blew out the hole with compressed air, undid the plug, threw in the new one and thats it. Dont forget to add some anti seize and dielectric grease.
