When looking at the front of the GS you will notice where the Lexus Logo is the vents are vertical lines....

Below that where the fog lights are and directly below where the front license plate would go, the air vent is different, like a bunch of X's.

Does anyone know if they make a vent for the lower area that matches the main vent where the Lexus logo is ?

I hope that makes sense, I have no idea what these areas are called.

Thanks in advance.

I am not sure if Lexus specifically makes one, but I have seen ones like the one you are describing chromed and in black (as stock).
Just look around they're out there.
