Exclamation Spark plug gap

Greetings all. Got a quick question here.

I changed my spark plugs on my 2013 N/A hatch and I used NGK plugs.
They came pregapped at .044 and I regapped them to manual spec which is around .035. I noticed the gap when I removed my old plugs they were around .044. One was ~0.47, but they were consistently 0.044.

Just wondering if i'm running the true correct gap.

Any help appreciated.

Sounds correct.

You can recheck by looking at the emissions sticker under the hood, that should include plug info..

The bigger gap sounds about right= .044 maybe .045 you'd have to look as Roger mentioned the sticker under the hood. It is a cop & dgi system.

IIRC the gaps are smaller for the current GDI version than for our earlier models Bruce, his numbers sound correct.

If I could run the .044 gap that'd actually be easier in the future. Regapping was a real pain.

Hypothetically, could I run the pregapped .044 without issues?
I haven't driven the car yet to see if I can tell a difference with the gap to spec.
