Hey Scotty!
my wife has a 2013 Jeep Grand Cherokee with a 5.7L hemi V8. I don’t know what spark plugs are in it but I suspect copper or nickel. Can I replace them with platinum or iridium? (Some hemi forums say no, but NGK website says yes)
thanks!

Sure you can, I’d recommend the iridium plugs because they last the absolute longest!
Just make sure you use the same size that’s made for your vehicle. Your owner’s manual may put you in the right direction too, look it up under the service/maintenance section.

They are probably platinum. Iridium will last longer.
Don't know why there would be an issue. Maybe someone else can help answer.

I think iridium is stabler than platinum.
