i know that your not supposed to tighten up the spark plugs alot when installing them. i dont have a torque wrench just a damn socket wrench. how tight does it have to be when installing them. do i just tighten them enough to where i can kind of feel the tightness then i stop?

 

its 13ft/lbs .. you really should get a turque wrench but i guess you can tighten them till they stop then give them a quarter turn

 

ok i will do that.

 

tighten by hand, then quarter turn on wrench
