My airboxes are not connected/sealed to the inlets. Even if they were, the flanges are no smaller than the actual pass through ports to the OEM boxes.
My experiments on another similar design (sealed) on another car showed that the flow up dual 2.5" hoses was enough to pretty much eliminate any restriction at the airbox outlet, and actually show some positive pressure on a Magnehelic gauge..
