Do you need it? Depends on how much boost you are running.
Is it recomemneded? YES.

What it does?

It lowers temperature of the air going into your engine from your supercharger.
Cooler air = denser air = more air = more power.
It also allows you to run more boost before your engine explodes. Why? No idea
