I know that if you do not clip the rear glass hatch down, when you hit 60-70 the glass pops upwards and stays horizontal. A clear indication to me that the std intercooler and rear spoiler probably do not work very effieciently and the air flow just runs off the roof horizontally backwards.
As I understand it, the standard intercooler works on the vacum behind the car (pulling the air out of the engine bay), which doesn't relate to the lift.
