Description

The Brisk GR14S Silver Racing Spark Plug is engineered for high-performance, demanding ignition conditions, including forced induction and nitrous oxide applications. Its design utilizes a 1.5mm silver wire center electrode, which is the best material for heat and electrical conductivity, allowing for rapid heat dissipation and maintaining a lower spark plug temperature. This results in a more powerful and consistent spark, crucial for igniting high-octane fuel mixtures and ensuring a faster, better flame front and flame speed.

MIA's Description

The Brisk GR14S is a racing silver spark plug designed for forced induction and nitrous applications. It features a smaller diameter silver core and an open spark hook type earth electrode for enhanced performance with high-octane fuels and alternative fuels like E85, CNG, and race fuels. Silver's superior heat dissipation results in a lower spark plug temperature and a more powerful spark, leading to faster flame front propagation and smoother operation at higher RPMs.
