Hello group I wanted to know what type of spark plug you put in the car and how many brings our c43 amg, Greetings

We have 6. There isnt really any "upgraded" plug out yet unless you go with a silver core plug from Brisk.
OE interval is ~47k miles. Many have done them around (myself included) here and noted they were in excellent condition. Probably a conservative change interval, BUT with multispark system and high boost they do degrade more quickly, do not push them to 80k.
I went with NGK as they are the mfg for MB on this size plug. If you want the MB logo printed on it, then order that one.
