I recently purchased a 2014 Ram 5.7 with 159K miles on it. I was given a folder full of maintenance records
but I cannot find any plug change at all. The truck is running well. But I am trying to get the truck up to my standards of maintenance.
I ordered NGK Iridium IX spark plugs and I read NGK's specs that say the plugs come pre-gapped at .43 or .44
I used a feeler gauge set at .43 and the gaps on just two of the plugs were over .50.
I quit there and returned the plugs to Amazon........were they ripoffs? How can one tell?
