2012 Spark Plugs... 50,000mi or 100,000mi?

[NCRaineman]

I've had my truck for about 2 months now and it just hit 52,000mi. I've been reading here and see that some folks are saying plugs are good for 50,000mi and some are saying they're good for 100,000mi. Bought this used and have no idea whether or not the plugs have been changed on it, but do know that changing them is an... ... ... involved... ... ... procedure.

Looking at the CarFax report I got at purchase this truck has a pretty extensive service history at a local dealer but I'm not seeing anything about plugs. If 50,000 is when they need changing I'm gonna go ahead and do it soon, may actually take it to the dealer to have it done just so it goes on the service history in case I do decide to sell it years down the road. Anybody know how much that would set me back?

Thanks!

Don't be sorry, info is good. If 30k was the recommended interval for plugs on a 2012 I'd imagine mine have been changed once already and should be good to 60k. I will pull one out this week and take a look at it.

Thanks!

Edit: Would it be of any benefit to upgrade to iridium if I've got to get them changed, or does this particular Hemi prefer the cooler coppers?

Stick with the copper and change every 30k.
