The Brisk Silver Racing Spark Plug (GR12S) is engineered for enthusiasts who demand maximum ignition efficiency. Utilizing a high-conductivity silver center electrode, this plug ensures a stronger, more consistent spark compared to standard copper or platinum alternatives. Designed specifically for high-performance applications, the 14mm thread and 18mm reach provide a precise fit for engines requiring a heat range of 12.
The silver center electrode offers the best thermal conductivity of any precious metal, allowing for a wider heat range and improved durability under extreme racing conditions. Whether you are building a track-day monster or a high-output street car, these plugs help optimize combustion, leading to smoother idling and improved throttle response. The tapered seat design ensures a perfect seal in compatible cylinder heads, preventing compression loss during high-RPM operation. Trust your ignition system to the experts at GGCRACING for your next build.
