Brisk Silver Racing plugs have a better ignitability than conventional performance spark plugs, and offer better performance and reliability in high boost, nitrous or high compression applications. Silver is an element with the most free electrons, and is the best electrical and thermal (heat) conductor of all metals! Better than gold, copper ...and many times better than Iridium. The Brisk Silver Racing plugs have a fine wire center electrode (not just the tip), which gives more room for insulator between the center electrode and spark plug shell. More insulation results in a durable spark plug with high dielectric strength - the most important spark plug parameter in forced induction applications. Brisk Silver Racing spark plugs have helped Tim Lynch and Steve Petty to keep the A/F mixture lit and set 4 New World Records since they started using them in their extreme 3,000+Hp 6.66sec @ 223.5mph Twin Turbo 10.5 Outlaw Mustang, and can do the same for you. In street applications, the greatest advantage is a powerful spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load and excellent anti-fouling resistance under light load operation.
