What's the part called???

[whatup]

I am looking to purchase a Benz part, but can't find it on any webpage or internet search. It is the vent/duct that is in the hood (not the front grill). It is up by the windshield (close to the wipers)...I have tried typing in Benz Grille/Benz Grill/Benz Duct/Benz Vent. I don't know what else to try to type in to get this part. I would show a picture, but I can't even find a picture of this item.

I think I can help, but first I need to know the year and model of the car we are dealing with. if its the "grill" on top of the hood of say a S500, its called a ventilation screen
