How much torque should there be on spark plugs? I just replaced them and the car runs better but I'm wondering if there is a "best fit" with them if I used a torque wrench. I don't think there is, but just wanted to find out...

Also, how much torque should there be on wheel lug nuts? If this is not consistant, could this be a problem? I'm thinking that there might be... I did my breaks and so far I don't have any problems, but I'm just checking before too much time goes by.

Thanks!

 

spark plugs-15 foot lbs
wheels- I give mine 85 ft lbs

if its not consistant then you may warp your roters

 

Cool - Thanks. I suspected about the warped rotars but was not sure about the lbs... thanks

 

i torque my wheels at 100 ft/lbs...it's pretty much standard at any shop on most passenger vehicles.

as for the spark plugs i go for what feels right...in other words i guess.

100? geez.

 

standard at almost any shop??? uhm what area do you live in? duno but there but out here in CA different manufacters specify different torque settings. So uhm, if your workin on a Geo Metro your torque setting is different from a Maxima or Altima or whatevers.

i would never recommend anyone to torque their wheels to 100lbs unless specified by manufactuer.
