Last week I tried changing the spark plugs and coils on my 16 328ix drive with almost 80k miles and was getting misfires left and right. FCP euro sent me a new kit and told me to toss the old one. I tried installing the original kit again and what do you know they’re working fine now. I’m not sure what I did differently but wow I feel great. Idk what to do with this new set now. Maybe I’ll just send them back to FCP since they were so cool about sending me a new kit no questions asked.
