Currently have around 40k on my Gen 3 engine. I've bounced between E85 and 93 since 10k miles and was curious on plug life. Since the Gen 3 is DI it can be alot harder on plugs. Most Ecoboost owners tend to change at 60k albeit a turbo engine vs N/a.

If its running great, and zero misfires, no need to change them. Do them at 50K?
