After scouring the forums, I came across a reference to these guys

Seems they have custom fabbed an air cleaner that is the same shape as a turkey pan, just a bit smaller. It has a K&N filter in it, with an aluminum top and bottom plate available with the Cobra emblem stamped in it. Guy said he thinks it flows around 900cfm and claimed it was the max flow you could get with a turkey pan & filter set-up (we'll see about that next time I'm at the dyno).
I ordered one and will post a pic when I get it in.
Thanks!
