If this one's wrong as well, then I spent a total of half a G for nothing.. lol.

I think some of us are jumping the gun here; more dynos with different setups (e.g. tuned 335i w/ oiled aFe filter, "other" dual cone filter intakes, etc.) are needed before we can come to the conclusion that these intakes actually lose power. As my wife says, "don't give up."
However, the thing that I don't like is the fact that with these "open, in engine" intakes, they are not fully a connected and sealed box system like the oem stock intake (so the outside air comes in directly through the grill, through the snorkel, and into a closed, sealed intake box, and then through the air filter to the engine); this means that these open intakes suck a lot of hotter air from the engine bay into the engine...that can't be a good thing.
Either way, I spent $319 on this aFe intake, and I'm going to try it for a month or two; if I see more dynos (especially on cars with a similar setup as mine) that show a loss and/or feel a loss myself, then I'll remove it, and put my oem stock intake + BMC drop-in air filter back on. This sucks!
