The resonance you are describing could be a couple things. First thing to try is loosen the three bolts that hold the air box brackets to the chassis. Push down on the box while tightening the three bolts. This gets the box sitting as low as possible. The only other thing is the air box lid itself. It's only two layers of carbon fiber and can have a tendency to "drum" from the air movement. There isn't realy any more room between the hood and air filter element to try and make it thicker or stiffer. It's just one of those things that happens.

Mike I believe it is the top of the box that is resonating. When you put pressure in the middle of the lid it is considerably quieter and you can feel it vibrating. davepk came up with an idea to add a support to underside of the lid, like a brace or something to keep it from vibrating.
