I have seen comments that if you install Iridium plugs in a 2013 hemi you need to upgrade the coils. True or false ? Thanks

Pull your original plugs and see which ones are in the engine. The older coils if you have copper plugs,will fire the iridium plugs,but if you can swing new coils it wouldn't hurt.I have seen comments that if you install Iridium plugs in a 2013 hemi you need to upgrade the coils.
