Question Torque spec for spark plugs

Anyone know how many lbs to torque spark plugs to on a 2003 Expy 5.4 EB? I've read mixed results but the search never said what engine it was.

Aircraft mechanic torque. Tighten it until it strips. Then back it off a quarter turn. LOL


Sorry, I can't help. Just thought I'd give you something to chuckle about while threading the socket/extension/universal joint/extension combo down to #4.

Alldata pro lists 13 ft/lbs (18nm) for torque. Labor time quote is 3 hours.
