Your Dealer's parts dept. should have no problem ordering them for you, but most likely they do not have them in stock... The Mopar number is in this thread

That does suck but at least there's not 16 of them.

The advantage, one set lasts 100 thousand miles, rather than just 30 thousand.... Most dealers charge about $200.00 or so to change them.... If doing it yourself your looking at between 3-5 hours in labor....
And from my experiance, I'm getting better gas milage and smoother engine idle
I think if you do the math, you will see the advantages

It would be great to use these plugs as some of you have, but I have been advised that they will not fit/function in a 2012 Ram 2500 Hemi as the engine is slightly different than many of you with the Hemi in the 1500. I guess it has to do with VVT that my truck does not have. Seems a bit disconcerning, but it is what it is. Maybe someone else can chime in and provide some add'l comments.

I'm 3000 miles away from the 30K and was advised by the dealer that the platinum plugs will work but the engine will act (in their words) "hinky" (must be one of those technical terms LOL).. AND they have seen someone who put platinum plugs in their Challenger Hemi and something with the engine went, and Chrysler denied the coverage.. Probably something not related to plugs, but seems like they take any excuse to not cover under warrentee. Since I have a 2009 with the lifetime drivetrain, I'm doing everything by their book for service just in case I have problems. Otherwise I would probably try the platinum plugs to see how they reacted. I did have one car that didn't like them so I wound up replacing them with the copper plugs shortly after. The estimate they gave me for the "Tuneup" was $500 with the copper plugs.. OUCH!

Just go with copper if you want cheap and shorter life, or iridium if you want longer life for a little more money(actually better value in the long run though). The "middle" plugs aren't worth bothering with.

It's a misconception that different plugs give more power. They all start off basically the same, then as the cheaper metals(copper) wear away you lose some performance. Iridium doesn't wear fast like copper so the performance lasts longer and stays more constant through it's life. If you dyno tested the same engine with brand new copper vs iridium plugs the power would be nearly identical. Wait 30k miles and do the same test and the iridium would hardly change but the copper would lose performance(not a ton, but noticeable).

^I agree, VVT has nothing to do with the plugs, it should be fine with iridiums.

First these Mopar Police Plugs are Iridium, not Platinum.
Second, unfortuneatly I don't have any additional knowledge about the Hemi's in a 2500 vs. the 1500. I would think they are the same, but I would go to different spark plug manufactures web sites, and I would compare their part numbers for a 2012 2500 and 1500 Hemi, if all their recommended part numbers are the same for both models, then you should have no problem using them... If they recommend a different plug numbers, then I wouldn't use these.... But any recommended Iridium plug should give you the same results.... Hard to believe that your 2500 Hemi is that different....
The only difference in recent Hemi's that I'm aware of, is that the bigger Hemi found in SR8 Challengers etc.... Uses a different plug than the 5.7 Hemi's
