My local Ford dealer want 78 dollars for the Bullit cone air filter. Looking at them they seem to have keys in them which fit into the CAI tray. So I am sure that not just any cone air filter will work there. Any suggestions?

Original equipment replacement air filter for 2008 Special Edition Mustang
I just bought a M-9601-B air filter from my local Ford dealer, who also is a FRPP dealer. $32.95. Mustangs Unlimited has them for the same price. The FRPP site (OpenDNS) has a listing of FRPP dealers. You are correct - the element is keyed to fit the M-9603-GTB CAI tray.
