Beru Ultra and Ultra X Spark plugs.
Double ignition reliability due to air-surface discharge technology
Sparking improved by four earth electrodes arranged in pairs in an X-shape.
Optimal combustion due to protruding spark position
Reliable cold starting:
Self-cleaning function due to variable sparking paths
Ideal operating temperature reached quickly due to conical insulator nose
Pollutant emissions minimised and catalytic converter protected due to effective combustion
Due to resistance to electrode erosion and interference suppression resistor.
The air-surface discharge sparkplug with nickel sheathed copper core and 4 ground electrodes arranged in pairs in the form of an X provide maximum ignition reliability in all operating situations.
The multifunction principle for optimal ignition reliability: various principles of operation are available for the formation of the sparking path air discharge, surface discharge and combined air-surface discharge. At the same time, the 4 ground electrodes are offset in height in pairs. On the left the path to one of the two lower electrodes can be seen, (surface discharge), on the right the two possibilities on one of the upper electrodes (air discharge and air-surface discharge). In this way there are six different paths for the ignition sparks.
