Superior Spark with Brisk Silver Racing

The Brisk Silver Racing Spark Plug (GR15YS) is the ideal choice for racers looking to improve ignition consistency and power. The silver center electrode is renowned for its exceptional electrical conductivity, which is significantly higher than traditional platinum or iridium plugs. This allows the GR15YS to produce a more powerful spark, ensuring complete combustion even in high-load, high-RPM environments. With a 14mm thread and 18mm reach, it fits a wide range of performance-oriented engines.

Technical Specifications

  • Electrode: High-conductivity Silver
  • Thread: 14mm
  • Reach: 18mm
  • Heat Range: 15
  • Seat: Tapered
  • Resistor: Yes

Silver is the best conductor of electricity among all metals, making it the perfect material for high-performance spark plugs. The Brisk Silver Racing series leverages this property to provide a hotter, more reliable spark that helps your engine reach its full potential. The tapered seat design ensures a secure, leak-free fitment in your cylinder head, which is essential for maintaining consistent compression. If you are looking to optimize your ignition system for better throttle response and overall engine performance, the GR15YS is a proven solution.
