Well the two airflows never mix - they're kept separate from each other. The reason for the intercooler is that the exhaust gases heat up the turbo, which the "cold air" then passes through and thus too becomes heated. The intercooler cools back down the "cold air," thus allowing the engine to run more efficiently. The intake is necessary as you want to select where the air is coming from, as grabbing it after its passed through the radiators and the engine block would substantially increase its temperature. It also allows for the placement of flow sensors, and air filters, to prevent debris and liquid from entering into the engine.That I know, but the air that is being put into the turbo only helps propel the turbine and mixes with the exhaust air which is already hot..hence why it has to go through an intercooler. If anything you'd rather have no piping and no restrictions at all do air can get directly to the turbo.
The air from this intake isn't going into the Intake manifold but instead mixing with the exhaust air...
