How does the Powerduct work?
I was wondering if anyone could give me a semi-technical explanation about how the Powerduct works to improve air flow. I know bigger doesn't necessarily mean more air flow and the pictures I've seen don't really help me deconstruct how it works.

I'm no expert, so take my opinion with that caveat in mind.
Logic tells me that the powerducts job is simply to expose a path for air to flow from the MAF sensor to the TB. I guess the idea behind some of the aftermarket models is to create a less restrictive/turbulent path for the air to flow.
IMHO, you should just stick with the stock one that came with your car. From what I have read, you get absolutely no horsepower gain. It is more of a cosmetic thing than anything else.
Again, this is just an opinion from a newbie.

If you look at pictures of engines that tuners have worked on, they have the stock air bridge and accordian coupler. As suggested earlier, these are probably just a cosmetic mod.

Increased airflow through the duct by making the internal surface smooth and few abrupt changes with can cause turbulence which reduces the total amount of airflow. The coupler eliminates the accordian stock one for the same reasons. If turbulance is present, the turbulent wave vectors are on a significantly different path or direction of the overall airflow into the throttle body and intake. These different waves will effectively brake or dampen the remaining air velocties and even create additional turbulance.
