Injen hands down. We have both the black and polished in stock. Let me know if you're interested.

None of them are truly cold air induction, they all take their air in from the same place the OEM intake does. SO it's really a matter of "which $200+ shiny pipe do you think is prettiest". Minor (peaky) gains, risk of hydrolock, silly pricetag.

The stock air box has a tube comming from the air box down around the wheel well. It draws air from there. The filter is still in the air box. Injen, K&N, Fujita, All are less restrictive than the stock air box and have pretty much the same gains.
The OEM airbox has an extension on it, which draws air in from the fenderwell. All of the CAIs position their filter about 6-8" below the OEM intake's opening. The thing is, just to the left of the filter is a square opening, which opens up into the engine compartment, just below the battery tray. So all of the CAIs draw their air out of the engine compartment, and nowhere else. Stick your head in there sometime and check it out.
As to the capacity of the intake, the most resrictive part of the OEM gear is the paper filter. The rubber upper piping is susceptible to heatsoak. Replace the paper filter with something higher flowing, and the upper pipe with something that won't soak heat, and you have removed the only two drawbacks to the OEM setup. All of the CAIs are aluminum. They are more than willing to draw the heat out of the engine compartment and pass it into the intake air.
A wise man once said, "Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock." Remember that, when you buy an intake for how it sounds, or the color of the annodization.

I agree that the aluminum piping on CAIs are prone to heat soak, but if you want performance and don't care so much about looks you can wrap it in pipe insulation from Home Depot or somewhere. No more heat soak, I've done it and can tell the difference. The aluminum also has tha advantage of allowing smoother air movements compared to the OEM tubing. As for intake location with the CAIs, it is true that they position the filter near the opening to the engine bay. But if you pop out the black plastic cover on the front bumper the filter is now able to get all the cold air it can handel. You can also tell the difference when you do this with a CAI, granted it is not much difference but you can feel something. So a CAI is a great mod to start with, it won't make you beat a WRX but every bit helps.
