What is the name of this part?
It's a vent and I am missing the one on the passenger side.
Would like to buy one but don't know how to name it.

 

It is a fake vent, does not actually vent, and when I looked for it on an explosion view, it does not show, it probably comes with the actual bumper...There are some aftermarket companies that make real vents that fit in there...so you can vent your brakes or run a hose up to your intake.

 

It is part of the bumper and if it is missing it means it was cut out.
