OK, I am seeking the honest, down to earth truth. I have read all sides of this issue and would like to know if OEM spark plugs are the right choice for a 2008 Commander Overland with the 5.7 Hemi. Some posts say the "exotic" plugs (iridium,platinum, etc) cause the engine to perform poorly and others say it performs better. Go figure. Does anybody have the "truth"? Thanks in advance.
