A message from Anthony at Livernois:
Jon,
Sorry to hear that, but glad to hear you've figured it out. The plugs we sell and suggest to run are the OEM Ford Motorcraft plugs that already come stock in your model year. The earlier 2010-mid 2013 models had an inferior stock Motorcraft platinum plug that Ford has since superseded with this newer iridium fine wire style plug that is also a heat range colder than the older platinum plugs. The newer plugs also have been gapped better from the factory now, which we then adjust further down to .030" to avoid any issues with spark being blown out from the elevated boost pressures our tuning provides. So your vehicle being a 2016 already has the updated stock Ford Motorcraft plugs that we sell, so you are all set there. Then if it feels like the truck is stuttering or hesitating at high RPM / boost , typically at the top of 1st, 2nd, and 3rd gear during hard acceleration, you know to pull the plugs and tighten the gap down to .028-.030" That is not as necessary now on these newer models since Ford has been doing a better job on their stock plug gap since they had so many issues on the earlier models. If you had a 2010-13 model vehicle, I would suggest to ditch your plugs for the newer version gapped to .030", but you already have the newer plugs we use from the factory and would know almost instantly if they needed to be gapped the first few times you went full throttle. Spark blow out from boost is something that you cannot miss typically, you'd feel the vehicle stuttering and surging instead of holding you back in the seat. Let us know if there is anything else we can help you with and we hope you have a great weekend Jon!
Thank you
Regards,
Anthony
