In case of multivalve technology, lean burn or direct injection, the flow conditions in the combustion chamber require reliable mixture ignition and optimal cold starting behaviour. BERU spark plugs were specially designed for these special requirements. Where the burn-off resistance and ignition reliability need to be very high, automobile manufacturers such as BMW, Peugeot and Porsche use BERU spark plugs with platinum electrodes.
