Platinum - Performance & Longer Life


0.3mm Diameter Pure Platinum Centre Electrode

  • Better performance
  • Better ignitability
  • Reduction in required voltage


Centre Electrode Diameter Comparison

  • The electric field is concentrated across a smaller surface area enabling sparking to occur at a lower voltage, resulting in reliable combustion with improved engine starting and acceleration.


Longer Service Life

  • Pure Platinum centre electrode gives a 25% longer service life over Super Plus.


Increased Fuel Efficiency, Smoother Idling' and Acceleration

  • Heavy duty tapered electrode for reduced electrode temperature, and improved access to air & fuel mixture.


Super Plus

Bosch Super Plus

Reliable Performance and True Value for Money: With 50% longer service life compared to OE spark plugs, the Bosch Super Plus with yttrium enhanced center electrode provides reliable starting and reduced fuel consumption.

Superior to all standard spark plugs


Pointed Ground Electrode.

  • Increased ignition reliability due to faster flash-over of the spark and ignition of the air-fuel mixture.


Electrode Wear

  • Proven in endurance and severity tests. Yttrium electrodes exhibit less wear than electrodes without Yttrium. Endurance tested over 90,000km with the same engine.


Long Service Life

  • Yttrium enhanced centre electrode gives 50% longer service life over standard copper core spark plugs.


Improved Performance

  • Uniquely shaped, profiled ground electrode improves egnition performance, fuel saving and reduces harmful emissions.
