from what i've heard people do not like the iridiums very much and they even throw a code, as far as the coil, the hemi's have a coil packfor each individual cylander and you won't find a better setup than that.
i hear you man....there are a bunch of folks running iridiums with no issues, but myself and dad have had problems, along with other people on this forum.....some trucks like them, some dont! luck of the draw i guess.....2003 ROCKS HEMI said:I had iridiums in two trucks with over 20000 miles of driving no codes ever. I had no problems. First truck was a 2003 Dodge Ram 1500 QuadCab Hemi 4x4 shortbed SLT. Second truck was a 2004 Dodge Ram 2500 QuadCab Hemi 4x4 shortbed Laramie. Both trucks had superchips programmers too.
Did you buy the plasma booster a while ago when it was hem ispecific, or did you buy the mustang part# that is supposed to work on our trucks?? I am interested in this mod as well.hemidup said:Yes, It doesn't create any additional heat. It produces a longer, higher amperage, multiple spark to help burn any unspent fuel in the combustion chamber, thus creating more hp.
