Overview

The Brisk GR14S is a spark plug designed for high-performance and racing engines. It features a silver fine wire center electrode and a tapered ground electrode, with a high-dielectric strength insulator. The spark plug is built for hard-to-ignite fuels and offers benefits such as superior ignition ability, lower required ignition voltage, and good resistance to fouling.
Show original supplier 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.
