Benefits of Silver Racing Spark Plugs

BRISK Spark plugs with Silver centre electrode of small diameter, especially are most suitable for engines powered by LPG and CNG as well as racing engines.

The use of gaseous fuel saves the users considerable financial resources and is more environmental friendly. BRISK Tábor places great emphasis on ecology and therefore developed the SILVER special spark plug range, which has been used for many years by customers from all over the world. The spark plug design eliminates problems caused by the different characteristics of LPG and CNG fuel from the original installation when running on petrol. The high thermal conductivity of silver offsets the higher heat stress without changing the thermal value of the spark plug and thoroughly covers the requirements of the engine even when running on petrol. The shape of the electrode and smaller electrode gap reduces the demand on voltage supplied by the ignition system. The open spark gap does not hinder propagation of the flame front and ensures perfect burning of the mixture, which is advantageous even when using the SILVER range spark plugs for racing engines.

Key Benefits and Applications

Construction
  • 1.5 mm Silver Fine Wire Center Electrode
    • Low ignition voltage requirements (easier for spark to jump over)
    • Reduces stress and wear on your coil and other ignition components
    • Fires properly even if partially fouled, where standard plugs will fail
    • Excellent for:
      • Standard and High compression engines
      • Forced induction applications
      • Nitrous applications
      • Methanol/ethanol injection
      • LPG / CNG Driven vehicles
      • Any hard to ignite type of fuel applications
      • High RPM race engines where is a short time for the ignition coil saturation
      • Beneficial even for old vehicles with a weak ignition systems and/or excessive oil consumption
Tapered or Cut-Back Ground Electrode
  • Provides sharp edges for easy spark discharge
  • Excellent spark exposure to the air/fuel mixture
  • Faster flame front propagation in the initial stages of ignition due to reduced ground electrode obstruction
High dielectric strength
  • Fine wire center electrode (not just tip) increases the thickness of insulator between the center electrode and the spark plug shell for higher mechanical and dielectric strength.
