Spark plugs gap and torque

Hey guys do u know what is the correct gap and torque on the spark plugs.
I read they are coming pre gapped and according to this :
https://www.newtis.info/tisv2/a/en/f...-plugs/5rctKot
it is 30 Nm.

I think the part number is: 12120039634

Sorry, didn't realize you were asking for an N55. I believe they are but not certain.

Thread on N55 spark plugs is M14, right? So they should be torqued to 30NM?
I'm reading conflicting numbers everywhere. I've seen 23, 27, and 30NM so far.

Also, does someone know the torque of the E18 strut-tower brace?

I hooked my car up to ISTA+ and saw the following:


N55 plugs are M14, right? So that means 30NM -+ 3nm, correct?

Edit: just got the OEM plugs. The box states 23nm -+ 3nm.
