Hey everyone, I’ve got a 2016 Dodge Charger with the 5.7L HEMI engine, and I’m looking to get a bit more performance out of it. I’ve heard that upgrading the spark plugs can make a difference, but I’m not sure which ones are the best for this engine. Should I go for iridium plugs? Are they really worth the extra cost? I’ve read that they handle heat better and last longer, but I’m also worried about the gap settings. Do I need to adjust them or are they good out of the box? Anyone here who’s done a plug upgrade on their Charger? Would love to hear your experiences and recommendations!
