The FSM says that, but then also specifies the torque!

After breaking the old plug using a large screwdriver, I tightened the new one with my thumbnail!

Those plugs get brittle from heat, I guess. According to Dupont, if they used modern engineered plastics like Zytel, they would last for 3000hrs. Sounds like we should be changing the plug each time system is flushed or say every 150k miles.
