In my past experience, Motorcraft and only Motorcraft in stock/ish trucks. If blown or juicing that's a difference story.

I read these zex plugs are good for bolt on performance parts they also make a different plug for boosted and juiced engines

Thanks for the confirmation. The only reason I asked was because all of the parts store web sites say they do not fit
