Duratec valve cover

Along with the new Typhoon ECU, I'll be changing over to "coil on plug". At what model year did Ford/Mazda change to this technology? Looks like I'll need to upgrade my valve cover to the later one with the coil retainer bosses.

A simple Google images search for "Duratec valve cover" showed examples from 2005, 2006, 2007 with the bosses in place. I have no idea what year specifically the change was made, but easy enough to locate some with the bosses.

Thanks. I was a bit hasty and found it as well.
