I install the same plugs before reading this thread. I had the exact same issue. All cylinders misfire.

When back to original plugs all better. Ngk ruthenium doesn't work on e92 m3

I have both. Not sure why it doesn't work. After this I dig some digging and bone stock cars also had issue. But at least we know laser platinum still the best plug.

DO NOT BUY THESE. Replaced my oem plugs with these and got misfires in every cylinder. I don't understand how these are advertised for our car.
