Technical Features
  • Reliable ignition: Combined air/surface gap technique. Ignition reliability by several spark paths.
  • Powerful: Optimal combustion due to protruding spark position
  • Cold start reliability: Self-cleaning function by surface gap spark technology.
  • Reliable:
    Quickly reaches the ideal operating temperature by a special insulator mount and intricate earth electrodes.
  • Environmentally friendly: Pollutant emissions minimised and catalytic converter protected due to effective combustion

The multifunctional principle for optimum ignition reliability: Different functional principles are available for the spark process – air spark technique, surface gap spark technique and the combined air/surface gap spark technique. The sketch shows the spark process with the Ultra X as an example and explains three of the 6 possible paths available to the spark here.


And the BERU Ultra X Platinum additionally offers:
  • Platinum central electrode Extreme burn-off resistance, reliable cold start, optimum combustion and utilisation of fuel. Consistently reliable ignition at high running performance.
  • Even more spark paths Constant air/surface gap spark technology: 8 spark paths, even greater ignition reliability.
  • Horn electrodes New electrode geometry for good mixture accessibility and open flame propagation.
  • Duplex insulator Smooth insulator body, combined with 2.5x leak current barrier on the insulator head for protection against sparkovers.
Our Tip

Timely Spark Plug Replacement Pays for Itself! Spark plugs are subject to wear and must be regularly replaced. Otherwise there is a risk of incomplete combustion, increased fuel output and increased pollutant emissions as well as misfiring. Misfiring can result in unburned fuel reaching the catalytic converter. This can cause irreparable damage to the catalytic converter!
