Air Box, what's that all about?

Why does the CSL air box make such a difference to noise and more importantly bhp?

All else being equal I have witnessed that if you flap is stuck shut the CSL looses 0-30 bhp between 5200-8000rpm levels compared to a normal working flap with sport on.

This proves surely that with sport button OFF you are loosing say 0-15/20 bhp between 3500-5200rpm when the flap is shut but that all kick back in when the flap opens.

BUT the question I am asking is why does the air box work and how does the ram effect work?
