Spark plug confusion
Hello everybody,
It has been awhile. Currently have a 2016 supercrew XLT Fx4 with the eco boost 3.5. Getting ready to replace the spark plugs but not sure what the gap is supposed to be. I have read that it should be set to .28 to .30 but then again have seen posts saying .50 to .52. I will be using the motorcraf SP520 plug that has a preset gap of .51. Now I see others that are pre gapped at .32. What should be the correct gap?
Thank you

I also have a 2016 F150 but I have the 5.0.
With that being said, the spark plug gag info for all 2016 F150 engines is in my owners manual on page 370.
