BRISK IRIDIUM PREMIUM+
260.00
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
