I have a mark VIII MAF that I modified to use with the tbird style cold air kits. As you can see in the picture I rounded off the edges that had the bolt housing so that a silicone coupling could be used. Also the inner, upright peice has been cut off to allow more air flow (matches the C&L style). I had this on my car with no leaks until I realized it was making my car run rich. This will require tuning to be used properly. Open to offers.
