Aren't the scoops sort of "channeling"/"forcing" more air into the intake system?

As to your explaination, pushing more air up the straw?

I have the red RPI scoops, not exactly sure if I felt a difference, car is fast as hell already. Maybe I did notice a better pull when doing highway runs (speeds above 80 mph...).
