Probably a dumb question but I'm gettin old...
I'm gonna change out the plugs next week - not sure if they have EVER been replaced. 17k miles on car. Can or should I shoot some penetrating oil down in there before I try to take them out? Would using a small drill driver impact be a good idea? I know to put anti seize on them before I put em back in - not sure if the ones in it now got it....
Anybody know the torque right off hand?
