Brisk Racing Spark Plugs - GR12S

Brisk GR12S Silver Racing Spark plug is designed for forced induction applications and nitrous applications. Brisk GR12S Silver Racing Spark Plug replaces NGK heat range 8. Most popular applications are modified Ford Lightining and Harley trucks, Ford Mustang Cobra & GTO.

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.
