Premium LGS Racing Spark Plug

The Brisk Premium LGS Racing GOR15LGS spark plug is engineered for tuned performance engines, racing applications, and vehicles running unleaded or alternative fuels. Its unique multi-ground electrode design and silver core provide outstanding performance in igniting over-reach mixtures, which are common in performance-tuned engines. The arcing occurs around a 360-degree perimeter, which is not mixture dependent, allowing for a larger gap at lower voltage levels. This significantly increases the ignition surface area. The silver center electrode is chosen for its superior heat and electrical conductivity, allowing for fast heat dissipation, a lower spark plug temperature, and a more powerful spark. This results in a faster and better flame front. Unlike single-electrode designs that require a homogeneous mixture around a specific point, the multi-earth electrode design of the LGS range is not dependent on mixture placement. These spark plugs are compatible with most aftermarket and OEM ignition systems, ranging from simple coil and distributor setups to modern electronic ignition and powerful direct ignition systems found in port and direct injection performance engines. They feature a patented firing tip design that requires no indexing or gapping. The projected design and tapered seat, along with a 14mm thread diameter, 18mm thread reach, and 16mm hexagon, are key specifications. The service life is rated at 60,000 km or 40,000 miles, and 50 hours for racing use.
