So I've been reading about the CAIs people have been building, took apart the stock system and came up w/an easy solution. Get a 6"Spectre filter and about 8" of 3.5" exhaust pipe. Put the exhaust pipe in the stock tube as a sleeve up to the IAT. It as a pretty tight fit but can be done. There should be an inch or so sticking out of the end, just put the factory clamp back on and clamp the new cone filter on the pipe. It seems the only bad thing about the factory setup is the corrugation causing disruption to the airflow, the sleeve should take care of this and give the aftermarket filter something hard to clamp to. I am hoping the stock tube will work as an insulator to the tube reducing temps and the IAT stays in the factory location with no drilling or modification.(It is dark and raining or I would get pics)
