I wonder if the Airaid box could be modified to keep it's better breathing, but adopt the cool air properties of the stock box. Why not close off the Airaid box top with a sealed lid or cover (have to make it clear so the pretty filter is still visible), then seal the front CAI opening (like the OE box does) with a soft gasket material so it can't leak hot engine compartment air where it meets the factory air opening in the front compartment wall. Make it draw exclusively from outside the compartment. For good measure the factory opening might be enlargeable or a supplemental air tube could be provided for even more air from the upstream side of the radiator. In short make the Airaid draw air from the same air source (upstream of the radiator) as the factory box...only with enhanced Airaid breathing and no Airaid leaks. Of course the easy way is to drop a K&N panel into the stock box, and maybe that's really good enough, but I love the thought of the free breathing Airaid. On another note, I also wonder if the reason for he convoluted way the airbox feeds the turbos through that Y plumbing is to keep the tube lengths similar for both banks. If it's not for that, ..... I don't have a clue.
