I had heard that at some point during the 08 model year Ford changed spark plug design used in the V10 to a design that was less likely to break when removing them. Does anyone know if that is true, and if so what was the build date of the change over.
Thanks
Bill
That is true. I don't know what the build date change was. You can tell if you have the new style plugs by the color of the coil boots. If you brown coil boots you have the new style plugs. If you black coil boots you have the old style plugs. I will try to find the build date info.
