best Spark plugs for C36 AMG

[cassard]

hi, I noticed I have a misfire at one of my cylinders when I push it down to 3500 rpm and up. (big lost of power over 3500 rpm and the sound of the engine change, almost like an old V8)

I'm going to check it, but I'm 90% sure it's my spark plugs, because it doesn't do it on the rain, (except if again I push the pedal down)

So I was wondering if you guys could tell me the best spark plugs I can get when I'll change them. Since it's not expensive I would like to buy very good quality ones.

Worst case scenario, if it's my wiring, how much can it cost and what wiring would you suggest me to buy ?

Thanks

Bosch Platinums are pretty good.

Really? huh, disregard what I said then. Unless the car is modified you are best off with whatever the OEM recommended model is. It's going to be Bosch, but I don't know what the recommend for the C36.

For the m104 engine, it is strongly recommended to stick with the OEM Bosch copper plugs. They can be found in online mparts stores for less than $2/ea. Other types of plugs are not in the right heat range and have an added resistor that makes them very susceptible to big problems in older engines.
