Hi all,
I have heard that Ford changed spark plugs for 3.5 EB for 2022, but that some late build 2021s may also have the new style. My 2021 has a build date of 9/1/21. Looking at Ford‘s online catalog, and using my VIN, show two part numbers. The difference is that the older style has a taper where the plug meets the head and the newer users a copper washer.
This is just a curiosity now and I guess the easiest way to find out would be to pull one. Does anyone know if this is correct?
