Hoping someone can help here. I had a part underneath my 2006 Infiniti M35 fall off due to rust. I've been searching the forums and service manuals and have not been able to identify it. Can someone look at the attached image and advise? It's directly below what I think is the splash guard on the right hand side. It's grey with a rectangular pattern and there's an identical part on the opposite side. If you're looking at the image it's near the bottom directly above the piping on either side.

Thanks,
Barry
