Hello all,
its 100k on my 2015 Ram 1500 5.7. Time to change the plugs. I had ordered a set, found out they were cooper tip. The plugs I pulled out was ILZFR5E 11. Sent them back, went back online found a set at Amazon SP143877AB. confirmed with Mopar online dealer yes those are correct for my 2015 truck. the plugs arrive. I pulled one out of the box and the NGK number is different, LZFR5CI 11. I cant seem to find any info on line about a sub forward on the plugs. Does anyone know if there was a NGK number change? These are an iridium plug, so I'm tempted to use them. its just confusing how the numbers done match, but it is correct from Ram sites.

Google for NGK numbers. You'll find the updated list on their site or image section of the google. Confirm them.

I did, i dont think this helps me. they are both valid part numbers. I would need to get a Mopar number for my plug and compare against the new listing ( AB)

Or Rock Auto sells them, about $100 shipped for a set of 16 (the cheapest I could find anywhere) and they’re legit OEM replacements.
