BRISK spark plug NAR14YS Silver Racing series

The BRISK NAR14YS Silver Racing spark plug is designed for racing motorcycle and ATV engines. Its key component is a silver centre electrode, which ensures reliable ignition even under extreme thermal loads. The special spark plug design resists the high pressures and vibrations typical of racing. Thanks to the open spark gap and larger insulator tip surface area, the spark plug promotes complete mixture combustion and resists fouling.

Durability in extreme conditions

The silver centre electrode features high electrical conductivity and excellent resistance to high temperatures, ensuring reliable ignition even in the extreme conditions of racing engines. The overall construction matches this performance, built to withstand extreme vibrations and pressures. The spark plug features a special open spark gap design. This configuration promotes complete mixture combustion, while the enlarged surface area of the insulator tip prevents carbon build-up and extends the lifespan of the spark plug.
