Gapping ngk 97506 plugs for a stock s63 setup

[AnotherM]

Hey guys,

I have read every thread i can find and cant really find a clear answer. I have a new set of ngk 97506 plugs that were for my n63, but i am now planning to install them in my 2013 m5.

The car is stock and is going to stay stock for the near future. I want to run the gap as close to stock .032 for fuel economy, but also want the car to run as smoothoy as it should.

Should i gap these down or keep them at stock gap? What are the positives to gapping them down? Im staying stock so i dont imagine having any blown out since boost is stock.

Gap them at stock .032 or .030. Both are ok.
