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.
