2018 F-150 2.7 with Lots of aftermarket, OEM spark plugs (sp578) (1 step hotter then these plugs) we’re going quick. The truck is very sensitive to the spark plug gap. I called MPT and asked them if there was anything that would help with how fast they were going out. They recommended these which surprised me, Ford does not mention this (only for 3.5) I trusted them and purchased a set.. bet damn aftermarket part so far, lol got tired of replacing them. Truck runs a little smoother, my gas mileage seamed to go up a little, probably my imagination , either way they work for me. They are also Pre-Gapped no need to adjust! Hope this helps someone out.
