Instead of just one throttle body per bank, each cylinder has it's own which allows for a higher volume of air to flow. Not only this, but instead of having air pulled from one source for multiple cylinders, having ITB's also insures that the air paths are more direct and less constricted by turbulence.

And, as we all know, the D15 is notorious for being such a monster that it needs large volumes of airflow.
