2014 Limited 5.4 3 V Plugs question

[Vdubnick]

2007-2008 was the end of the breaking plugs... easy to check, new plugs have COP with brown boots, old had black boots.

I will let a dealership do this as I can't anymore. Going to use Motorcraft plugs and new coils. Just want to do preventive stuff to this unit to make it last as long as possible. Appreciate all of your advice.
Thank you

Is this a reliable place to buy factory parts ?
