LGS Racing Spark Plug

The Brisk Premium LGS Racing ROR15LGS spark plug is engineered for optimal performance in tuned engines, racing applications, and vehicles running unleaded or alternative fuels. Its distinctive multi-ground electrode design, combined with a silver core, provides superior ignition capabilities by creating an arcing perimeter around the 360-degree electrode. This spark plug is constructed with a silver center electrode, which is an excellent thermal and electrical conductor, promoting lower operating temperatures and a more powerful spark. The design requires lower voltage for ignition, contributing to faster and more efficient flame front propagation. Unlike single-earth electrodes, the multi-ground design is not dependent on a homogeneous mixture at a specific point, offering greater versatility. Key specifications include a 14mm thread diameter, a 25mm thread reach, a 16mm hexagon size, and a tapered seat type. The spark plug is projected and features a resistor. Brisk claims a service life of 60,000 km (40,000 miles) or 50 hours of racing. It is compatible with most aftermarket and OEM ignition systems, from simple coil-and-distributor setups to modern direct ignition systems.
