ASE Question Of the Month
Which is correct?
You’re correct if you answered B!
While it may have helped in years gone by, the use of any type of anti-seize compound is frowned upon by most spark plug manufacturers. The material used to manufacture the threaded portion of the plug are already resistant to corrosion making the practice obsolete. Technician B is also correct in that the torque applied will be inaccurate and excessive compound could even isolate the plug electrically, causing a misfire for that cylinder.
