1.0 Ecoboost Spark Plug Service Intervals

[hypojam]

Howdy Everyone. What is the Ford service interval for the plugs?

 

I noticed on the PumaSpeed website that they recommend changing the 1.0 ecoboost engines plugs every "12-15k for high boost engines, 20k for stock motors"

I have 28k of Very hard miles on my 1.0 focus of which 7k have been with a superchips maps. So i remove one of the plugs (does require an unusual plug socket size):

 

And what do ya know, The gap is at the 0.7mm spec! and side by side with a new plug i cant see any wear. Looks like its burning nice too.

 

So lesson of the story yours plugs should definitely be more than fine at 28k especially on a normally driven stock tune engine.
