Bit OT because it's N54 engine but check this out...

Wonder why they redesigned their intakes to be sealed now ?

I should note that their intake for the M3 uses the factory sealed box yet it still didn't deliver any power.
Here's the description from their website:
This Stage 2 air intake system produces 18 max horsepower, 15lbs. x ft. torque and out-flowed the factory intake by 41%. This unique intake system is designed to use the factory intake box to seal the intake tube and filter and tube against unwanted underhood temperatures while increasing air flow and velocity for optimum performance. This air intake system features a washable/reusable conical Pro 5R air filter for maximum flow and filter life, a dyno tuned intake tube and all the hardware necessary for an easy installation. This system is truly a silent killer.

Unfortunately, after five or six runs, we weren't seeing any gains from the new parts. In fact, we were struggling to find the stock output. It was decided that a few miles on the ECU would help it recalibrate to the improved airflow.
We returned to aFe's dyno several weeks later and, as the graph shows, we still couldn't find the promised horsepower increase. The aFe personnel were clearly disappointed and suggested a problem with the dyno was a possible cause.
So while we didn't make any power, there are lots of reasons to use the aFe components, which would probably see more benefits from a car with software.
