RE: Spark plug replacement?
If money is no object, consider the Denso Iridiums (ITL16), NGK Iridiums (LZTR4AIX-11), the Autolight XP Iridiums (XP5263), or the Champion Iridium (9403). They should net you at least 60k mi between changes. The Bosch have a bad rep in some circles due to faulty resistors that may have been fixed in more recent versions. I've used the Autolite XPs with good results and they're typically 1/2 the price of some of the others. If you go with the copper cores, the Champion Truck Plugs have a good reputation.
BTW, I've used Bosch plugs and most of the above brands over the years in a variety of applications, other then longevity, I've never measured any difference in MPG or acceleration between any of them.

RE: Spark plug replacement?
NGKs are great plugs, but I just don't want to change them every 30k mi. Have you guys ever run them in this application for 60k mi or more ? I ask because the in many applications--not the Hemi--theyr'e considered a 100k mi plug--eg, the Toyota Highlander. I've seen some folks on various boards asking whether they should change their plugs with over 70k mi for a Hemi and over 170k mi for a Toyota. I can understand the Toyota with its Iridiums. The Hemi though! Makes you wonder if the 30k mi change interval is overkill on the Hemi. BTW, the Hemi owner with 70k mi didn't even have any performance problems. He was just asking cause he thought their time might be up. He probably could have gone farther.
