Gold (Professional) Glow Spark Plugs

Specially designed to give diesel engines the heat they need for cold starts, these ACDelco Gold (Professional) Glow Spark Plugs will maintain ignition in all cylinders, improving throttle response and reducing exhaust emissions.

  • The BERU GN-type glow plug can function under higher voltages, up to 15.5 volts, that would normally burn out many other glow plugs.
  • This plug protects itself against overheating by limiting the electricity flowing from the battery to the plug, in proportion to the increasing temperature.
  • From 21 mm to 40 mm of reach, ACDelco Glow Plugs offer a wide range of chamber reaches for a variety of applications.
