If you went 100K on the OEM plugs with no problems why not stick with OEM plugs? Spark plugs ain't rocket science; they either work properly or they don't. I remember all the hype in the 80's and 90's about platinum plugs, multi-electrode plugs, aircraft engine type plugs, etc. I tried them all and never found a bit of difference on engines that burned unleaded fuel.

 

I just did the plugs on my Wife's 2012 with 90K on it. I went with the OEM Motocraft plugs went in with no problem. A friend that has a repair shop has always told me to go with OEM on anything built after 2008. He states that everything is so optimized at the factory now that you can't really do any better in the aftermarket. Also tolerances and specs are so precise on newer motors that it's not worth the risk using anything else. Just his opinion but I trust it. Good luck.
