SPECIAL SPARK PLUGS WITH SILVER CENTRE ELECTRODE
Spark plugs with silver centre electrode, special design, adapted to high thermal load, vibrations and pressures.
The open spark gap does not hinder propagation of the flame and ensures perfect ignition of the mixture. Unlike standard spark plugs with the same thermal properties, the silver centre electrode makes it possible (thanks to its higher thermal conductivity) to use a larger surface area of the insulator tip and hence ensure longer protection against contamination with conductive deposits.
