Hello , can you help me please ? I have a mercedes s 500 coupe 2015 c217 455hp i need to change the spark plugs cand you tell a good model ? What ngk iradium ix code  is compatible with my car ? Thanks 


Where are you located Europe? I think you have M276.824  engine. If so then: NGK Laser Iridium Spark Plug  SILZKFR8D7S  is recommended.  Gap is preset.


I’am from Romania - Europe , vin number of car is : 


the ngk v power is ok for my car ? 

NGK V power are copper plugs I belive while the recommended is laser iridium. Most likely the car will run just fine, but make sure to change them every 30k miles or so.

You have some code from NGK V POWER and from BRISK RACING what is compatible with my car ? Thanks 

is not problem i change at every 30k . 

I don't have part number for NGK V Power or Brisk but I have it for Bosch which are quite cheap and you should be able to find them in Romania.

SPARK PLUG BOSCH - 0242140521


For bosch if found for my car bosch double iradium . And i have one more question in Romania i don’t found disc brake front and rear from brembo you have some code ? I found just brake pads 


Sorry for the late reply. Just checked and they do not make rotors for your car. They do make brake pads though as you stated.

There is not that many DIYs on  the C217. Are you planing on replacing these parts yourself or are you going to have a mechanic do it for you?

For the spark plugs I would stick with OEM to be honest. As far as the brakes and disks sure upgrade if you find something. While spark plugs are not going to make a difference if you go with a more expensive type. The plugs that in the car already have been tested for best performance. The only advantage that you may gain from more expensive spark plugs is that they will last longer. But then they will cost a lot more that OEM, so not sure if you are gaining anything. Just my opinion.
