What you are referring to is the factory inlet portion of the assembly that connects to the remainder of the fuel injection air cleaner assembly.

The fuel injection inlet is not connected to the carburetor, therefore, it does not act like a ram air system. I doubt it has any effect on the performance of the engine since it's not connected directly in any way or form to the carburetor. It's removal will not effect the performance of the car.

You are correct in your description, however there is a performance increase with that inlet vs no inlet. It directs cooler frontal air towards the carb. I think the car needs to be a Z to utilize that piece.
