The side gills vent hot air out of the engine bay.

On a similar note, the hood bulge will probably help with cooling so I'd be glad to have it. On the E9x M3, the V8 engine fits fine without the hood bulge, but it's there to allow more air to flow over the top of the engine to keep it cool so it's possible that they tested the car without a bulge and are now testing it with one to see how much of a difference it makes but who knows.

I could be wrong about the V8 fitting under the E9x hood, but I remember reading that the bulge was mainly for airflow over the engine.
