6.0l Captains Choice - Spark Plugs - tjmoberg - 10-15-2021
2012 - 3100 Coronet
6.0L Crusader Captains Choice
Having a hard time trying to find what the original AC Delco - Double Platinum spark plugs are and what is the Iridium replacement?
I tried several auto parts stores and have been scouring the Web, not getting much luck…
Appreciate the help!
