The engine fan creates relative low pressure inside the engine bay. The air will creep in from anywhere it can, including around the top edge of the intercooler if it isn't well sealed. The 911 is the only car on the road that you can pre-cool the intercooler while sitting at a stop light. Just rev the engine. To give you an idea how much air that fan moves, try standing behind your car bare-footed and rev it up. I bet you won't stay there long :-)
