2014 C350 upgrades
Well not only am I a new member here, I'm the owner of a new 2014 C350 Sport sedan. Are there any performance upgrades for this car or the M276 engine that won't kill the warranty? I've put in a K&N filter and had a Magnaflow X-pipe installed already, but that was mostly for the sound only since neither of those is really a performance upgrade. I know I could add a tune if anyone is offering one for this car, but I'm not sure it'll be covered unless it's from Brabus or Renntech and I haven't seen anything on their websites about the C350. Ideas anyone?

There's a tune, although I personally would not do this unless I could have it done in person at a local shop. Personally I'm waiting for headers. As for the K&N filter...did you happen to get this one?
K&N 33-2985
I'm due for a 40k mile service and it would seem as I'm also due for an engine air filter replacement.

Did you replace the filter yourself? If so, what did you do with the 2nd filter immediately after the main one?

I did replace it myself. I didn't see a secondary filter when I pulled the main factory one. I don't believe there is one as I don't see any place in the intake ducting that would allow for one. If there is however, it's still in place.
