Best deal out there is http://www.amazon.com/Autolite-XP532...2009&carId=001 Download the $2.00 rebate from Autolite. 5 year guarantee on the plugs. Just installed a set couple days ago.

For the hemi - Cheapest I've found for the stock plugs are from dodge-wholesale.com part SPLZFR5C11.
I haven't found the NGK plats (PLZFR5B13EG) designed for this motor sold anywhere yet.
If you have the 4.7, half are copper (above) half are plats, you'll likely have to get them from the dealer. Stay away from the E3's, people have been known to have issues, the hemi's are sometimes very fickle about the plugs used, best to stick with the OE NGK's.

The stock does work fine. So does platinum and or long wearing iridium. Benefit is not having to replace for three times longer then inexpensive nickel tipped plug. The Platiumn PLZFR5B13EG plug used in 5.7 Hy-bred is for a while dealer only. At some point it will over the counter. I was going to use them until I did some digging into product and such. I think they were $10 bucks or so each best I recall.
