This talk of gains with different filters is absolutely insane, one question. Who's got any hard information on this? Hmmm... kinda what I thought... I've yet to see anything tested on any of these filter/intake combos with any real accuracy to it. I hear a lot of theory and such, but it seems people are only picking and choosing the parts of the theories that they want to use. If Vita has something planned, that's one thing. For the rest of you, you need to gather some real information on superchaged engines, how they take air in, how a short ram works, how a CAI works, etc. I know I like to hear myself talk, and I know there's people that know more than myself, but I can't believe that were still talking about intakes.
If the intake is going to pull all the air into the car that it wants, then there is no reason to touch anything. Right? The only real way to increase the intake performance of a supercharged engine is to provide positive pressure at the intake source. You can do this several ways. One way, is with a CAI, for instance:

Has good pictures and explanation of what a CAI is really doing. We can argue this if anyone wants, but the TRUE intention of a CAI is to provide mild air pressure at the intake. I've said this before, and most people ignore me, but I'm gonna say it again.
So anyone that states that the intake is going to pull all the air it can, shouldn't be touching the intake, and if they are, then they don't believe themselves. If you're doing it just for the sound or looks, then it's different. If you're looking for more power, you have 2 choices, a CAI, or a Ram-Air setup, that's it. You're not going to do anything else to increase the power. I'm sure I'll be jumped on for this but who cares...
