Brisk Silver Racing ER12S is a special
racing spark plug that Brisk supplies to European Rally teams such as
PRODRIVE and its heat range is equivalent to NGK heat range 8. Ideal for
turbo, supercharged, nitrous and methanol injection engines.
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.
