Baller Garn Posted April 18, 2017 Baller Share Posted April 18, 2017 Does anyone know what torque you should tighten the spark plugs too on a 2007 325 Indmar engine? Link to comment Share on other sites More sharing options...
Kdinger838 Posted April 18, 2017 Share Posted April 18, 2017 I think it was somewhere around 10-15 ft/lbs. i usually index the plugs, just don't snap them! Link to comment Share on other sites More sharing options...
303Skier Posted April 24, 2017 Share Posted April 24, 2017 I wouldn't torque them, just get them nice and tight. Link to comment Share on other sites More sharing options...
Baller jhughes Posted April 24, 2017 Baller Share Posted April 24, 2017 Plug torque is definitely a "feel" thing. I wouldn't trust a torque wrench in this application. Link to comment Share on other sites More sharing options...
Baller teammalibu Posted April 24, 2017 Baller Share Posted April 24, 2017 My dad was a mechanic for 60 years and he would tell ya to crank er down till she snaps and back it off a quater turn! course he also said to find a short stick a penny in the fuse and just watch for the smoke Link to comment Share on other sites More sharing options...
Baller Jordan Posted April 24, 2017 Baller Share Posted April 24, 2017 I've always run them in finger tight then tighten a half turn Link to comment Share on other sites More sharing options...
Baller oldjeep Posted April 24, 2017 Baller Share Posted April 24, 2017 Depends on the plugs, for those with crush gaskets I usually snug down finger tight and then 1/4 turn. For those without gaskets more like 1/8 turn. Link to comment Share on other sites More sharing options...
