I have a 2013 Ram 1500 with the 4.7 engine. I am needing to do the 60,000 mile spark plug service and wanted to get some opinions on the type of plug to use. I realize that the manual doesn't call for platinum or iridium plugs, but I would like to hear from those who have actually changed to these type of plugs and what your results were? I know we all have opinions on the matter, but I would like to hear from those who have actually used them, and whether you had a good or bad result. Thanks guys.
