I had just posted the other day in my thread about my misfire. Just upgraded to the one step colder NGKs gapped at .028”. I’m all stock, no tune. Just a JLT passenger side catch can and a weep hole. My Motorcraft plugs were garbage after only 15k miles, and cylinder 1 (one my my misfires) had a nasty carbon track. All of the plugs were already worn up to ~.034” from .031”. 2015 Expy w/ 105k miles.
Motorcraft plugs are trash for the EBs.
