M157 1 step colder spark plugs part # ?
This is the one I used. I had great results with it right off the get-go but after several thousand miles I just got a misfire code. I am running constant meth/water injection so I’m not sure if that’s to blame or not but I believe Dimon said he got some random misfires with these compared to OEM.
