BERU Ultra X Titan. The Spark Plug Innovation with state-of-the-art Electrode Geometry

High-tech-petrol engines need high-tech spark plugs: The new BERU Ultra X Titan sets standards in performance, durability and fuel utilisation.

From Ultra X came Ultra X Titan – and with it the most streamlined range of spark plug products in the industry

That now consists of 15 types in total: 6 of the already established Ultra X spark plugs – supplemented by 9 new spark plugs which jointly form the Ultra X Titan line.

The common denominator: the highly erosion-resistant titanium alloy

In the case of the 9 new Ultra X Titan types the ground electrode is single-pole and is worked in an innovative Poly-V shape. In the case of the 6 established Ultra X spark plugs the X shape of the electrode was retained and their erosion resistance reinforced by a titanium alloy. The Ultra X Titan range of products are available under the abbreviated designation UXT 1 to UXT 15 in new optimized packaging.

Good to know: The 6 previous Ultra X types without titanium electrodes (abbreviated designation: UX) are compatible with the new Ultra X Titan range.

Challenge of combustion chamber pressure – this is very exciting

The modern gasoline engine operates at a higher combustion chamber pressure. This increases the demands on the spark plug. The higher the combustion chamber pressure, the greater the power of the spark must be – as a condition for a reliable ignition of the fuel-air mixture and an efficiently operating spark plug. This is where the spark plug innovation BERU Ultra X Titan is setting new standards: with a highly effective combustion – thanks to the combination of several new design features.

The power of the Titan: high resistance to erosion, longer service life

The highly erosion-resistant nickel-titanium alloy of the ground electrode provides the innovative Poly-V design – in combination with the tapered platinum ignition tip – with an important condition for high ignition reliability, dependability and longevity of the new Ultra X Titan.

The Poly-V ground electrode: increased ignition reliability, fuel-efficient combustion

The innovative Poly-V design: 5 sharp edges which are actuated in a continuous cycle by the spark. This means: low breakdown voltage and 5-fold electrical point effect – resulting in improved spark-over. In conjunction with the highly erosion-resistant titanium electrode, a long-term constant ignition performance is ensured with optimized fuel utilization and fuel-efficient combustion with correspondingly lower emission values – with significantly higher wear resistance and a service life up to 60,000 km. Therefore,not only are the maintenance specifications of the vehicle manufacturers completely fulfilled, but they also are usually surpassed.

Corona discharge: innovative technology for reliable ignition

This intentional predischarge prevents the electrical short circuit – between high voltage and electrical ground – which can occur particularly in the start phase due to the resulting electrically conductive soot. In conjunction with a thin, cylindrically shaped insulator foot tip the engine starts quite reliably even under adverse conditions – such as at extremely low temperatures or after driving short distances.

Technical Features of Ultra X Titan
  • Extremely reliable ignition: With a high erosion-resistant nickel-titanium alloy: filigree ground electrode in specially developed Poly-V shape for extremely reliable ignition.
  • Cold-start reliability: Center electrode with platinum ignition tip for excellent cold-start performance.
  • Reliable: Corona ring for systematic predischarge and stable ignition.



The innovative Poly-V design: 5 ignition tips are actuated in a continuous cycle by the spark – and ensure high ignition reliability and fuel-efficient combustion with long-term constant ignition performance.

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!
