WHY ARE WE YELLING?!THE STOCK ONES
I do forget about the tunes and can definitely see how that would shorten life dramatically.I'd argue that in THESE twin Turbo direct injection motors, what makes a spark plug a "good" spark plug is far less about longevity than might be true in other motors.
But I'm also willing to agree that all of these motors are not equally demanding of their spark plugs. The driver and the tune/fuel demands can vary dramatically the combustion chamber environment, as well as the demands on the plugs.

You can literally drive this truck around and never get into the boost.
I'm not saying that's how I drive my truck, but it is absolutely possible for the circumstances on the road to render it NA for considerable lengths of time.
And I'm convinced that lots of folks, based on the way they drive, don't see much forced induction time on their trucks.
Now contrast that with a typical nice weather day and I'm out on a few errands and several times I light the boost gauge up to MAX. And several other times at say 7-10lbs.
The wear on the plugs during NA miles, even though they are direct injection miles, must be a fraction of the wear at the moments the combustion chamber is at 18 or 19psi, along with those injectors firing their 2000+psi pressure washer fuel streams at the end of that plug.
So it's not surprising to me that the lifespan of plugs in these motors could easily vary by 100% or more, depending on use.

BC the boost and fuel is turned up plus heavy footMeh, I have almost 93K on my 2015 and if still has the original plugs. Drives just fine and I've yet to have an issue. That said, I'm gonna change the plugs in a week or so before it gets hot here in Arizona. Don't understand why people change them so early...and often?
Is that your choice or what 5 Star recommends?Found some sp-542's $60 shipped to my door, a little pricey but I don’t mind, actually helping the guy out during these difficult times, He sells a variety of parts for the F150

Not sure about 5 star but it's a one step colder plug and since I run my e30 tune somewhat often figured I'd throw those in.Is that your choice or what 5 Star recommends?

LUCKY! Been looking but can't find them.Found some sp-542's $60 shipped...
