Ugh. another member lowering the performance of his vehicle to gain turbo whine and poorly filtered air to the engine.

lets see some pics of it installed on your car.

you understand the stock air filter flows MORE air than the car can possibly use right? I understand that the rattling broken mount is SUPREMELY annoying, and hearing that turbo whine is appealing to say the least, but it will get annoying after time, and the foam/oil filters really cannot filter the volume of air a diesel ingests!
I would route the smokey air back into the intake as pgirngo suggests. I'd also change that filter to at least a paper element, and install a heat shield to surround it, and get a fresh air intake routed into the box.
