Has Ford finally released a one piece plug for the 3V engine?

 

I think they made the switch with the 08s. Not sure. I just went with the Autolites.

 

made the switch when they changed head designs. which was sometime in late 07 for the 2008 models. i think it was late october because i have an early oct 07 (08 yr model) car and still have the old heads. lucky me
