Will this work on a 2015 ford taurus sho 3.5l ecoboost?

Yes, I have them certainly installed in my 2015 Taurus SHO. They came gapped perfectly at .030 which is the latest recommendation for the 3.5 ecoboost.

Are these already properly gapped ?

F150 ecoboost are supposed to be at 28 so always double check

Will these fit my 2016 expedition with the 3.5 turbo eco boost? and will they come pre gapped?

Yea they will fit and noticed they are pre gapped to .28-.30

Are these the original sp542 ? Or the new replacement?

Yes these are the SP542 plugs. Ford discontinued the 542s and went with the performance version only now. The markings on the 542s and these plugs are exactly the same.
