That will work just fine. It's basically the same intake use on mine, and it's also used on C430 if I'm not mistaken. Mercedes part #1120901101

The front shroud is another separate part; Mercedes part #1120100467

I bought mine brand new on parts.com for ~$100 shipped. The stealerships demand $170. At least my local one did...

Pics are in my gallery. Mine has been painted though; OEM is flat plastic.
