I have a C250 2013 and at 67k miles.
I understand the tranny service is recommended at 70k.
When do I change the plugs? I changed engine air filter at 50k (miles).
Any tips or recommendation for plugs if I decide to tackle it myself?

It should be in your service manual...but for the M276 it is 60k miles.

Genuine meaning has the three pointed star printed on it. If it weren't for the lifetime warranty and my certainty that I'll be taking advantage of it more than once, I likely would have gone with the Boschs as well, especially given that the factory plugs were Bosch branded. Did they have the model number printed on them, by chance?

I'll see if I can look up pictures in my archive...but from memory, everything was identical...brand/model number and all. The ONLY difference was the stock ones had the 3 star emblem printed on the backside as well.
I got most of them changed today. The last (of course) plug that I pulled out of the box was an NGK. I'll have to hit up FCP for a replacement.
All of the plugs I removed from the car had Bosch printed on them, but with "Platin" on the back instead of the three-pointed star like the ones I bought. They must have been replaced at some point which is a bit surprising given the mileage. It felt like they had antiseize on them and the torque to remove them was pretty different among the lot. Dunno if it means anything, but there you go. The model number stamped on the metal base was the same, though.

I bought Bosch plugs #YR8NPP332 (0242140512-879) from German Auto Supply, they confirmed for my car the OEM is bosch.
After replacing the plugs, I noticed the original plugs are NGK made in Japan (PLKR7B8E-NGK94716).
I guess FCP Euro lists the correct NGK for my car.
Don't really see any difference between NGK or Bosch.as far as the performance goes.
Wish I had taken pictures of my used ones when I had them done ~77k miles - they were completely toast. The main electrode on 4 of 6 of them was completely gone and there was no evidence of the platinum puck on the side electrode remaining (MB spark plugs may not have them after looking at pics above). Was getting misfires bad enough to trigger the CEL on 5 of 6 cylinders anytime the car sat overnight in temps below 35-40.
This was almost 10 years or ~77k miles on original plugs and they were toasted enough to trigger a CEL, no misfires when driving at temp it was just for the first 5-10 seconds after a cold start. No issues the prior winter on the original plugs.
So after a quick message to FCP about the lone NGK plug I received, they shipped me a box of new plugs. However, upon opening them, they were all NGK. I sent another followup message asking if this was right since I had pulled Boschs out. Here was the reply:
This was a change from Mercedes themselves over to this plug type. Ill be honest with you I have had much better luck with NGK plugs over Bosch in the past so I would absolutely recommend using these. The one thing I would double check before [in]stalling is the threads for pitch and overall length just to be sure there was no error on their end.
So it sounds like Mercedes switched to NGK at some point. The thread and length look to be identical so I'll be putting them in soon. Just thought you folks would find that interesting. For reference, the part number on the boxes containing NGKs was 0041594903 and on the Boschs was 004159180326.

Check my post above and it clearly shows Mercedes put in NGK in my car.
Yeah, you were saying that yours came from the factory with NGKs, right? I was just adding another point of information that they're recommending a different brand than what it was originally equipped with, which might explain some discrepancies some folks are seeing.
After re-reading your post, are you saying Mercedes put NGK in your car at a dealership, while it came from the factory with Bosch?

My car has 60k and I replaced the plugs myself. The original plugs were NGK with Mercedez logo on them.
The car came with NGK from the factory.
I was just confirming your post that NGK is the official plug for this car now.
Don't know what they sell at parts counter thou.
