Most tuners will recommend the Motorcraft SP-542s. They are one heat range colder and gap is .026-.028. Trial and error on the gap. Try .026 then next change try the .028. Or maybe it is somewhere in between them that works best for you.
I hope this helps.

You bunch of "haters".
Yaw know me. I get the ".net" culture and wouldn't want much of it to ever change.
But I miss the days (era) before folks were labeled haters. In my day, it'd be "ornery" or "cantankerous".
Hater? I don't get it.
