Not running tunes I’d do 30k-40k changesWondering at what mileage everyone changes spark plugs? Mine is 2018 2.7L with 25,400 miles , no tune run 87 octane gas.
I do think if you're not having issues longer is no problem, my 2.7 I never changed the factory plugs, and that was running an E30 tune the majority of the time. Had no issues at allI’ll be doing mine around 60k. Also not tuned. Longer then most will tell you. Mostly because it runs like new still and gas mileage has been the same. When I do it I’m sure I’ll post pics and see how big the gaps got.
vs what?So the 580s are basically regular heat right? Not a step cooler

I put 30k on a 2018 3.5 in about 13 months. 10k of those miles were pulling a 7500 lbs trailer all over states east of the Mississippi. It runs like a scalded dog ,I mean "strong" . On the interstate it was get 26 without the trailer, and pulled that 7k around like nothing. The only thing I did was change oil on time.Wondering at what mileage everyone changes spark plugs?

I did mine at 60k and everything looked great. The factory plugs looked surprisingly good. I was originally told that the ecoboost eat plugs and dirties oil but I have not had an issue with either.I’ll be doing mine around 60k. Also not tuned. Longer then most will tell you.

I’m expecting the same as you. But early maintenance isn’t a bad thing. Makes me feel good.I did mine at 60k and everything looked great. The factory plugs looked surprisingly good. I was originally told that the ecoboost eat plugs and dirties oil but I have not had an issue with either.
I agree. I tend to over do my oil changes but this is the nicest vehicle I have ever had. Plugs are cheap too.I’m expecting the same as you. But early maintenance isn’t a bad thing. Makes me feel good.
