I have a set of used coils off my 2014 SRT8 6.4L Challenger. (Had 58,000 Miles)
I changed them out because I had a slight miss and didn't want to change just one. So one
of them may give you a miss, but I don't know which one it is. (Could be one of the Spark Plugs!)
I am also throwing in the '16' Spark Plugs.
Make me a 'REASONABLE' Offer!
