To pressurize the box would require that air horn to be exposed to the front of the car, and I’m not sure that it could really provide a decent level of pressure. If it is instead under vacuum from the engine, this would essentially make it a multi-part CAI with the filter enclosed to reduce noise levels. It would also probably not posess the resonance of a CAI like the AEM, and lack the AEM hump.
not boost pressure per say, but not the best flow. moving from the smaller to larger area slows gas velocity
