Hey guys,

I was cruising around the highway loop a few weeks ago when something that appears to be like a block of wood or brick came flying out of nowhere, (probably came from the truck hauling stuff in front of me). Fortunately it went under the car and not through my windshield or through the radiator. I still heard a loud thump and a cracking sound right after it went under so I pulled over to do a quick check just to make sure it didn't rip a hole on the radiator or anything that would cause important fluids/oil to leak.

Now there was no leak and it was kinda hard to tell but it didn't seem like it did a lot of damage so I drove home and on the way I noticed this whooshing sound which I've never heard before and was kinda annoying so I jacked up the car right after I got home to check underneath and for sure it did break this plastic air deflector/splash shield under the chassis exposing a gaping hole on the aluminum frame which was probably the cause of the continuous whooshing sound while traveling at highway speed.

I've scoured different part sites (gmpartsdirect, 7zap etc.) and it doesn't seem to be listed on any of the parts diagram I found, so
I was wondering if anyone knows or could maybe help me find the part number for this because I do a lot of highway driving and the whooshing sound really annoys me.

Sorry for the very long post. Here's the picture of the part I was referring to.
