What are these called ?

I bought a 2015 ML350 Base and didn't realize that the two plastic fire wall covers behind the motor where missing. Anyone know what there called and possible part numbers. Thanks in advance

engine bra...kidding. you need to get those or water will be splashing everywhere in that area and it might find it's way inside the cabin.

...And that's why I always take photos of the engine bay (and elsewhere) right before mechanics work on them. In almost every instance, panels/covers/shields, fasteners, cable/hose/pipe brackets, dust caps, grommets, electrical connector clips, seals, and even a bolt or screw, etc. will go missing or get broken...and, they usually do not tell the customer or just forget. That's just the reality of letting others — even experienced master techs — work on your vehicle.
