Go Fleiter Posted June 5, 2022 Report Share Posted June 5, 2022 (edited) I couldn´t find the recommended torque value for spark plugs, not here in the tech tips, nor in the resorces or in the Service Manual. Anyone knows beyond just own experience? Edited June 5, 2022 by Go Fleiter Quote Link to comment Share on other sites More sharing options...
andyd Posted June 5, 2022 Report Share Posted June 5, 2022 To be honest I've never torqued a spark plug........I just tighten them, personally I think that using a torque wrench on spark plugs is an opportunity to strip the threads in either the cylinder head or on the spark plug........my Oz 2 cents worth.........andyd 1 Quote Link to comment Share on other sites More sharing options...
Go Fleiter Posted June 5, 2022 Author Report Share Posted June 5, 2022 well, so did I and my mechanic too... Only once in 27 years one became loose on the road Other informations ? Quote Link to comment Share on other sites More sharing options...
FarmerJon Posted June 5, 2022 Report Share Posted June 5, 2022 (edited) A torque wrench is NOT a breaker bar!!! Set and used properly, it will not strip threads any more than any other hand ratchet, even in aluminum. They serve ONLY to measure how much torque you are applying. I use torque wrenches every day, on everything from M4 screws in titanium and aluminum to great big suckers in cast iron. If I start stripping threads and breaking fasteners I should be fired. All that said, I usually just eyeball it with sparkplugs in an iron head, and save the torque wrench for aluminum heads with plugs in tricky places where my "feel-o-meter" may get out of whack. https://ngksparkplugs.com/en/resources/spark-plug-installation Edited June 5, 2022 by FarmerJon 1 Quote Link to comment Share on other sites More sharing options...

Bryan Posted June 5, 2022 Report Share Posted June 5, 2022 Usually once it seats hand tight, then I always did a 1/4 to 1/2 turn where it was snug with one hand on a socket wrench. Not holding to the very outer end. Not as hard as you can pull with one hand. https://www.sparkplugs.com/plug-torque-settings-2 Quote Link to comment Share on other sites More sharing options...
Sniper Posted June 5, 2022 Report Share Posted June 5, 2022 The box the plugs come in usually states what he spec is. What Bryan posted is usually what gasketted spark plugs calls for. I used Autolite plugs, attached is their torque specs. torquespecs.pdf 2 Quote Link to comment Share on other sites More sharing options...
Go Fleiter Posted June 5, 2022 Author Report Share Posted June 5, 2022 thanks for Your help! and well, to find the result for a very special detail on google is NOT easy. You must have the right keywords or You fail. And if I ´m annoying, just don´t stress with an answer! Greetings! Go BTW: I had expected to find a Plymouth specification Quote Link to comment Share on other sites More sharing options...

Go BTW: I had expected to find a Plymouth specification it was no stress any more than typing 'spark plug torque' was into my search engine....if I was totally put off by your question or considered it annoying I would not have even bothered to look in your behalf or to paste the link....if you were based in the US....yes I would likely never responded.....so many folks come here first and wait for a reply that may or may not be correct when they could have all the facts, not just the guesses or how another person did it or what they may think is right, but actual data. As for Plymouth specification... Quote Link to comment Share on other sites More sharing options...
