Brisk’s Silver Racing Spark Plugs are the best solution for high performance and racing engines. These plugs offer the best thermal and electrical conductor of all metals, Silver, which provides an unmatched transfer of electricity and heat, resulting in the most powerful spark. Silver racing spark plugs feature many benefits commonly used in forced induction applications, applications where the ignition system is pushed to the limit and applications with hard to ignite fuels such as alcohol, LPG, Nitro-methane, etc.. The ‘spark’ produced is so powerful that it burns nanoparticles of the silver center electrode, which further increases the spark energy and ignition ability. Silver racing spark plugs are the most versatile spark plugs produced by Brisk!
