boozy 0 Posted June 6, 2019 Share Posted June 6, 2019 Hello. Doing new plugs on my 13 Spark soon. Just need to know a good torque setting for the new plugs. I am using the ACDelco stock plugs. Thank you! Link to post Share on other sites
Duncan 5 Posted September 5, 2019 Share Posted September 5, 2019 Bump...does anyone know the torque specs for the plugs? Lil' Wednesday appears to have a bad coil pack (P0301 code), so I'm going to replace that and do the plugs at the same time. You know, since I'm already in there. Also - damn, these coil packs are expensive! Like $80 each for the ACDelco part - off-brands aren't much cheaper. Link to post Share on other sites

Bobby MSME 100 Posted July 12, 2021 Share Posted July 12, 2021 (edited) In my younger years I must have changed 100's of spark plugs. Never used any torque wrench. All I did was tighten the spark plug with the usual manual wrench with gentle force. Never had an issue. Spark plug is not subjected to mechanical load. Just has to be tight enough so it does not get lose from engine vibrations. Torque values should not matter much here. But I never had to deal with a spark plug and coil combo situation. I have designed thousands of bolts subjected to extreme loads. There it was critical to torque the bolts to create tensile pre-stress in the bolt. That increases fatigue life of bolts. And prevents getting lose. Edited July 12, 2021 by Bobby MSME Link to post Share on other sites
boozy 0 Posted August 15, 2023 Author Share Posted August 15, 2023 According to my local Chevy dealership, 15ft lbs is the torque recommended for the spark plugs. Link to post Share on other sites
