Spark plugs - what gap on N55 M2

I cannot find any info anywhere on what should be the gap on the stock M2 spark plugs?

I know some here have done this DIY already, hoping someone can point me to a link explaining what exactly I should set the gap to (stock tune, stock spark plug).

Good advice I received in another thread was to never install spark plugs without checking the gap first, but can't find the info on what the measure should be anywhere, lol!

Can't find my notes but pretty sure it was 21 or 22 thousanths. All plugs were too wide out of the box.

Thanks. If you can find where you got that info, I would appreciate it.

Also, did you get OEM plugs from BMW, in the BMW box? Just curious to make sure same plugs.

I went NGK, 2 steps cooler as I'm going to be tuning it and have a Dinan turbo. Factory gap though.
