Description
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 giving 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. These Silver Racing plugs work well with most aftermarket and OEM ignition systems from simple coil and distributor through electronic ignition and powerful direct ignition systems found on modern port and direct injection performance engines.
- Fires properly even if fouling occurs, common standard plugs failure
- Silver centre electrode, best thermal (heat) & electrical conductor
- Lower voltage requirement
- Reduces wear on coil, leads and other ignition parts
- 1.5 mm Silver Wire Centre Electrode
Typical use cases:
Tuned and race engines.
Alternative fuel cars.
Old vehicles with weaker ignition systems and/or excessive oil consumption.
