Is this the right part number for thermostat?
So I did some research on various parts sites, and have found some conflicting information, so before I drop $115-$150 on a part that might be wrong, I'd like to know if someone could be so kind as to verify whether these are, in fact, both viable replacements for my exact car model, which is a 2009 C300 4matic Sport. Also, if both parts are compatible, is it a big risk (quality-wise) to go with the Wahler instead of the MB part?
4834100d (Wahler), or
2722000115 (Mercedes)
Appreciate any help!
