[s-cars] Torque wrench for spark plugs recommendation

Actually, it depends not on whether it is a click-type, but rather if
the torque wrench is a micrometer style or split-beam style.  

The micrometer style uses springs to set the torque and must be stored
at its lowest setting so that the spring is relaxed, otherwise it will
take a set and affect the calibration.  The split-beam style of torque
wrench doesn't use a spring and can be stored at any setting without
affecting the calibration.  The split-beam torque wrench is also more
accurate.  

Both types of torque wrenches are available with a click head.  Though
the vast majority of click type torque wrenches are the micrometer type
so it's a fairly safe generalization.
