I've searched a few threads but haven't been able to find a definitive answer.

I don't think I've ever seen a specific OEM gap, I stay between .026-.028".

Service manual says 0.031" (0.8 mm)

Is that in the ST supplement? I wouldn't see a turbocharged car having that large of a gap.

Just the regular Ford service manual. Says 1.6 ecoboost, so I don't know?

You said service manual so I assumed you were talking about the physical manual which is actually for the na model. Whatever online reference you're using is probably correct.

Oh ok. Yeah its the factory service manual on DVD.

Mine were .028

Mine were .028

Two of mine were 0.030 and two were 0.032. I split the difference and gapped them all 0.031. I think I will be okay with that.
