basically increases the diameter and volume of the inlet so that the engine can receive the air that it requires more quickly and freely and therefore increases throttle response and increases sound etc. Not a massive amount of bhp increase, probably none at all.

thinking of this, would be great to get the better throttle response, but does it make the engine extremely loud?
