Default Ecoboost New Plugs
59M miles. Put in new plugs. It's like a new truck. Much better response at partial throttle. Pulls harder at full throttle.

Damn! I'm amazed you got that many miles out of the OEM plugs, mine was having rough idle on cold start and surging at 29k miles, changed them, much better now

I believe even stock Ecoboost need new plugs at about the 40K mile mark, by at least the 20K mile mark if you run a tune.
