If it is necessary to widen the gap, do so with a tool that only pulls back on the ground electrode without touching the center electrode or the porcelain. To close the gap on a plug, gently tap the plug, electrode first on a hard surface.

Autolite doesn't recommend adjusting the plug gap more than .008" in either direction. Beyond that slight adjustment, the ground electrode and center electrode won't align properly, hindering spark plug performance and drastically reducing plug life. 

  • Due to the fragile nature of their electrodes, special care should be taken when adjusting the gap on fine wire plugs.
  • Gapping should never be attempted on multi-ground plugs.
