Brisk LR11SL Replaces:
Brisk Silver Racing Spark Plugs have a smaller diameter silver core and conventional open spark hook type earth electrode give an outstanding performance in igniting high octane fuel mixture associated with alternative fuels like CNG, LPG, Propane, E85 blend, Alcohol, LNG, Race Fuels and Nitro.
Silver metal is the single best material for a spark plugs core electrode, as it can dissipate heat fast, resulting in overall lower spark plug temperature and a more powerful spark.
The stronger the spark the faster and better the flame front and flame speed giving smother higher RPM range in engines.
Our Silver Racing range works well with most aftermarket and OEM ignition systems form simple coil and distributor through electronic ignition and powerful direct ignition systems found on modern port and direct injection performance engines.
