If those scoops helped, they'd be original equipment.
The turbo is sucking up air, the only way to boost intake efficiency is to enlarge the intake pipes themselves.
Imagine sucking air through a straw: even if you put a funnel on the end of the straw you won't suck in any more air. The amount of air you move is dependent on your lungs (the turbo) and the straw (the intake piping).
But if you like them, install them.
