If you guys haven't changed your stock plugs, even if your stock and or have more miles than mile.. do it asap!!! These cars make a lot of power even stock and put a lot demand on the stock plugs.
Ironically every BMW I've had and serviced….the mechanics have always said the same thing - Bosch plugs are utter garbage. I just got my M5C a couple months ago but I'm assuming I'll be changing them somewhere between 12-14k from what these past mechanics told me.
