Supertack - the euro snorkel seems like it could work, but I am wondering the following: how will air start to travel in an upwards direction? If air can go straight towards the brakes, or go through the little outlet at the top towards the intake area, I don't think it'd decide to go upwards.

I personally would not spend $90 on it. A similar contraption can be made involving a hose, some strong scissors to cut through the brake duct, and retrofiting it with the snorkel. The best way to increase air flow, in my opinion, would simply be to remove the brake duct entirely and put a hose in its place that leads directly towards the intake. Air has no choice but to go in that direction.
