It matters more than you think, especially because of the supercharger. Your number one goal is to avoid KR while making the most power as possible. To achieve this you want as cool as an air charge as possible and to do that you want to ensure that the air entering the supercharger is as cool as possible because the supercharger is going to heat up the air a lot.
The only time I'd say the difference would be minimal is if you're working with an inter cooled setup which will likely negate some of the gains of a cold air intake. On a non-intercooled setup though, you want the coolest air wherever you can get it.
