wjjeeps.com says they need to stay OE... Copper plugs or preignition will start.
i work at napa, most of my co workers, and some of the mechanics i deliver parts too say that it won't matter if i throw in platinum or double platinum like i want too. so they will last a little longer.
Platinum has less conduction than copper... making it last longer. Only thing better than copper to conduct is Silver. Stick with OEM. They have it that way for some reason or another lol
Ive heard alot about 4.7's and 5.7's being pretty picky and not liking platinums in them.
Yeah i've heard of people having issues with Platinum, I would use the Champion Copper core but Autozone did not have them in stock so I went with another brand but they are basically the same thing as the Champions, copper core .40 and they have worked perfect for me. I think I paid 1.40 each? I think as long as you stick with a .40 copper core you should be good.
Well my computer at work... I work at napa. It says the gap is .40 but wjjeepss sayys it's .35? Input? And I'm gonna throw copper in there, prob autolite, I'll let you know how they work out.
How long did it take all of you to do them with the 4.7??
