ShoBoat tested the Airaid setup on his ride. Apparently the weatherstrip supplied with the kit was not sealing the intake box from the engine compartment, thus compromising performance. He added on a foam weatherstrip to seal against the hood insulation, and that did the trick. Might be the way to go for you also.
There are a couple of custom intakes in development, but no release schedule or dyno/track performance data yet.
