I posted this up on SVTPerformance a little while ago and buried in a few threads here on this forum. I have had enough people contact me about it that I figured I would just make a thread with the information.
The M-6067-GT part number is a Ford Racing part number that has been discontinued. However, the coil covers sold under this part number are the OEM coil covers from the Ford GT supercar. These coil covers are still available under the OEM part numbers!
The part numbers are:
4G7Z6P067AA
4G7Z6P067BA
The cost is $94.24 each from Tousley Ford Parts.
