WARNING:

  • Max. tightening torque: Between 20 Nm and 25 Nm (Excessive tightening = risk of electrode breakage).
  • These spark plugs are only recommended for racing uses.
  • Because they are a little longer than a "classic" spark plug, make sure it doesn't touch your piston during assembly (otherwise add a second washer under the spark plug).
  • you may need to check your carburation setting because the combustion is optimized here.



BENEFITS:

  • Semi-surface discharge with high potential = MORE POWER
  • Discharge at the richest point within a 360-degree perimeter
  • Patented spark plug design - no indexing
  • Integrated and retracted electrode
  • Silver central electrode - Better thermal and electrical conductivity
Brisk Racing spark plugs are designed to maximize the benefits of the high power factory ignition systems used on high performance 2-stroke engines. The exclusive design of Brisk spark plugs provides maximum spark exposure and unlimited access to the air/fuel ratio. This is a must for racing engines where it's essential to maximize combustion for maximum power.
