My M2 with FBO, Dinan turbo, Dorch HPFP, and running the BM3 Stg 2+ E30 OTS map with E47 fuel didn’t like spark plug gap at 0.020”. Regapped to 0.026” and the car runs perfect.
I did switch to 97506’s but mostly bc I can return used ones to FCP Euro for a refund, which I’ve already done once.

My car flat out rejected the 97506 plugs. Blew two of them up on a WOT pull... Went back to OEM plugs at stock GAP and zero issues. I think the NGK's are overrated. I'm sure they have their place, but not for my setup. |
FYI- for this past year there have been many counterfeit NGK 97506 spark plugs out there. They appear identical to authentic plugs. Guys report that they might work for a few thousand miles and then fail. I heard a few similar stories with Bosch plugs. I would suggest to anyone not to buy spark plugs from eBay or from any individuals. I've gotten them from FCP Euro and from Burger.
