I am not going to say that this system is an advantage but, even if it was, it would not likely show up on a dyno. If he sealed the box to take advantage of the "ram air" effect of the stock snorkel, that would only appear at speed, where you could have ram air. Putting a fan in front of the car will not provide enough pressure to make a difference.
