Re: Active Aerodynamics
Without those inlets the only cooling inside the engine compartment would be hot air coming from the radiator. To aid in cooling the engine compartment area these inlets would allow some, but not much cooler air into the engine area. Better than hot air and better than nothing. The flaps would prevent air escaping too much and going up and into the intake manifold inlets when stationary.
Well that's my theory anyway.
