...have you ever switched out the stock copper plugs with iridium plugs? I'm so done with replacing these things @ 30k miles. I've been on Ram Forums and hear both sides. Platinum's don't fare well is pretty much unanimous since plats don't dissipate heat as well. Iridium does much better.
Anyway, just checking if anyone here has had any luck with the high end plugs. I just figured the engineers threw coppers in there for bank since it costs $300 - $400 for them to change the plugs.
