18 N-m (13 lb. ft) for new spark plugs according to Chilton (See the attached Guide). Pauls fixit guide says you go by the feel of the spark plug.

Note: Change the .txt extension to .doc in order to open the file correctly

Forgot, always use a bit of Never-Sieze on plug threads (but who really ever does). Ford back in the past decade was notorious for snapping off plugs or stripping threads (dissimilar metals).image.jpeg

I use Anti-Seize on plugs among many other fasteners.

I mostly like using the Lawson Anti-Seize Stick.

Spark plugs I prefer installing by feel.

New plugs usually need a little more than old plugs because of the crush washer.

If I had to guess how much force I use I'd say 15 ft-lbs with new plugs and 10 ft-lbs on old plugs.

Yeah, antiseize, and I use a short or stubby ratchet when installing to help prevent overtightening (normal or long length OK for removal, if space permits). I haven't had a car with an engine that had spark plugs with a crush washer since the 1960s - are they really still being used? Anything I have worked on in decades uses a tapered seat - I usually put a tiny amount of antiseize on my finger and lightly apply some to the spark plug seat
