It is all about what you want to accomplish. The air box is mostly about cooling efficiency. They will have a smaller opening than OEM. They will have short splitter and lowered in the front quite a bit to decrease drag. They will have undertray or a flat floor that also reduces drag due to less turbulence under the front of the car.
In road racing you are looking for mechanical grip and downforce to keep the car planted, there is a trade off on drag a top end. Straight line you want to reduce drag while optimizing mechanical grip, but you need enough downforce to keep the car planted.
Straight line is for fast cars, circuit racing is for fast drivers. To each their own, you know what I prefer!
