What does the Jeep shop manual specify for torque on the spark plugs? Every other vehicle I've ever had has that on a sticker in the engine compartment.....plug gap (for stock plugs) and torque....but not the KJ. It just has the plug gap and it's wrong (say 0.040" when NGK says 0.044").

Also posted this in the Tech Section under the changing plugs in the 3.7L topic, but need an answer quickly.

i dont know the torque but use thread anti-sieze on it, otherwise they wont come out (true of all aluminum cylinder heads.

I found a spec for the 3.7L off a WK board.... 20 ft-lb on the spark plug torque. I used my torque wrench, but it comes out to basically finger tight + about 3/4 of a turn.

3.7L V-6 2FR6F - 11G (NGK #) 1.1 mm (0.042 in.) 20 ft-lbs
from the factory 02 SM

Correct. Any automotive/motorcycle engine will call for spark plugs to basically just be a little past hand tight. All you really want to do is compress the gasket/washer. If u r using a torque wrench on a spark plug u r asking for trouble.
