If the F8LCRs are the wrong plugs then that is a joke. I will have to trade the car in for an NSX. I can't own a car that the dealer is not able to fix properly. BMW may have won the F1 race today, Way to go Ralf!, but the service dept. is about a light year behind Honda. BMW will not get a good recommendation from me and the local dealer will get a zero on the customer satisfaction. Doesn't matter that the car is fixed because I did everything I could to ensure the right parts are used by asking which plugs are right. The parts people said F9LCRs. I asked if they were in stock and they said Yes. If anyone knows if the two plugs are compatible please respond.
