Until about a month ago, I saw those same pictures. I laughed, because that design didn't work for me, and I know it sure as hell won't do much for them either. Besides the air filters that they have in that thing are like 250.00 ea. If I bought a filter that was 250.00. That thing better wash the car, and open the door for me when I get in. The other thing about it is, you still are using the same restrictive air box. I know it looks cool, but for performance its a killer.
Now the post I wanted to make....
Saskins, from what I remember of the pics of your first system, you used a K&N cone filter on the front. The problem with that is that all the air that currently gets channeled into the intake tube and is encased as it goes through the filter. With the cone, most of the air flows around the cone and isn't forced into it. Essentially you removed the ram air induction quality. Also, air traveling through the K&N (and similar cotton filters) flows perpendicular (K&N makes a big point of its ability to straighten out flow) and like all air flow areas, it doesn't like to make sharp turns.
For that matter I don't know exactly how the stock filters are angled in the air box and how much of an angle the air flow approaches them at.
Green filters twister essentially adds a short (very short) ram to the front of their cone, encapsulating it with incoming air pressurizing it and no way out but through the filter. Though I don't think the ram cone casing alone is enough to create much pressure differentiation without some more funneling in front of it to force higher volume of air through.
