Three threads holding the plug in place. One of Ford's better achievements. Plugs breaking and dropping in the cylinders too. That's why many shops charge big dollars to change the plugs on certain Ford's (V8's). The plastic intake manifold with the alternator stressing it was another inferior item which would break, sending coolant everywhere.
