Someone asked so here goes....I purchased a C&L 80 MM Mass Air and KN Cone
           filter. The mass air is actually a housing and I had to reuse the OE sensor. The kit
           comes with a 9" k&n air filter. The only thing I ran into is the housing is a smaller
           diameter then the factory air intake. I made an adapter from ABS plastic and siliconed
           it in with O2 safe silicon. (Silicon will kill O2 sensors in a heart beat).......there's a
           draw back...the check engine light comes on when the car idles for long periods of
           time and is temporary, won't even store as an error in the ecm. I paid like 300 buck or
           something and the thing works great. 14.9 with stock exhaust and 400+ lbs of stereo
           stuff. I am going to order a chip programmed for larger air volumes and maybe that
           will take care of it.
I got mine from a 5.0 and other fast fords, it is actually made for a cobra prior to
