BRISK IRIDIUM PREMIUM +
Centre electrode with Iridium contact and ground electrode from Yttrium alloy with copper core cut to spark plug centre.
Lower demand for voltage.
It opens spark gap into combustion chamber and suppresses significantly flame extinguishing effect at cold starts.
Iridium is even harder and stronger than Platinum
Cut back center electrode maximizes spark exposure into the combustion chamber and helps especially with cold starts.
High resistance to erosion enables the use of thinner centre electrode what does not impede the flame front propagation in the first phases of ignition and herewith contributes to engine power increase.
Zn/Ni coating for better resistance against corrosion
The copper core of the centre electrode increases the thermal conductivity and therefore it enables the insulator tip elongation by sufficient thermal value reserve of the spark plug
Copper is second best electricity conductor that enables minimal loss of energy producing a spark.
