That "mouth" isn't for the radiator, it's for an intercooler. Keeps the intake charge from the turbo from overheating and causing detonation as it is compressed in the engine. Colder air charge = more power, when tuning is correct.

OP, when you're not racing, you could certainly cover that up though. Unless you rev high all the time. Your Turbo shouldn't even really be spooling in street driving, so it's not really heating up enough to utilize an intercooler that much.
