    Brisk USA P5RR15YIR - Brisk Performance Iridium/Yttrium Spark Plugs

    Brisk Performance Iridium/Yttrium Spark Plugs are a combination of Iridium center electrode and specially designed ground electrodes with Yttrium alloy improving spark plug performance and lifetime maintenance. Designed with two platin contacts that significantly improves cold starts.

    Features:
  • Cut centered to center electrode assures the suppression of flame extinguishing effect at cold starts
  • Yttrium reduces the burning of electrodes and enables the flashover from ignition system
  • Copper core reduces the temperature by 100°C
  • Iridium contact on the center electrode assures a long change interval
  • Space between reduced diameter of center electrode and insulator tip enables a fast evaporation of fuel and prevents formation of soft combustion deposits on the insulator tip
  • The cylindrical ending of insulator tip enables self cleaning temperature after engine start
  • The ceramic mass with high content of AI2O3 increases dielectric strength
  • The copper core of the center electrode increases the thermal conductivity providing a sufficient thermal value reserve of the spark plug
  • The surface protection Zn/Ni extends the resistance to corrosion
