When I first installed my Icebox I gained some vibration at around the 2KRPM mark. Several months later, I re-tightened the screws around the box (which originally didn't fit perfectly) and now the noise is gone entirely.
I suspect that prior to this the airbox had been sucking air in from a corner of the box itself.
Since sealing the airbox properly, the setup is much quieter in all aspects of operation now (not just NVH). There is also much better low-down torque available. I can actually drive the car around in 4th gear at low speeds without any dramas whatsoever (only if I'm lazy or something else is going on in the car).
