Brisk Iridium High Performance Spark Plug - Summary of Advantages
The spark plug ground electrode is cut-back to the center of the center electrode which assures the suppression of flame extinguishing effect at cold starts and does not hinder the flame front propagation into combustion chamber.
Spark plug pecial alloy which is alloyed by Yttrium reduces essentially the burnings of electrodes and enables the flashover from rather long edge and low demand for a voltage supplied by ignition system.
Spark plug Copper core ground electrode provides better heat dissipation from the ground strap - reduces the temperature by about 100 C (212 degree F) which reduces the chance of pre-ignition and detonation, as well as reduce the ground strap hi-temperature burn-off and extenting the service life of the spark plug.
Spark Plug Iridium contact on the copper cored center eletrode assures a long change interval.
The space between reduced diameter of centre electrode and insulator tip enables a fast evaporation of fuel and prevents formation of soft combustion deposits on the insulator tip of the spark plug.
The cylindrical ending of spark plug insulator tip enables very fast achievement of spark plug self cleaning temperature after engine start.
The ceramics mass with high content of AI2O3 with increased dielectric strength of the spark plug.
The cooper core of centre electrode increases the thermal conductivity and therefore it enables the insulator tip elongation by sufficient thermal value reserve of spark plug.
The spark plug surface protection Zn/Ni extends the resistance to spark plug corrosion.
