Overview

The Brisk Premium LGS Racing HOR17LGS is a spark plug designed for performance applications. It features a unique multi-ground electrode design and a silver core for enhanced ignition capabilities, particularly in tuned engines.
Show original supplier description
The Brisk Premium LGS Racing HOR17LGS spark plug is engineered to provide superior ignition performance for tuned and racing engines. Its unique multi-ground electrode design allows for arcing around a 360-degree perimeter, increasing the ignition surface area and ensuring a more robust spark, even with richer fuel mixtures. The core of this spark plug is made from silver, which is an excellent thermal and electrical conductor. This allows for rapid heat dissipation, resulting in a lower spark plug temperature and a more powerful spark. The increased power of the spark leads to a faster and more complete flame front. Unlike single-earth electrodes, the multi-earth design of the LGS range does not depend on a homogeneous mixture being present at a specific point for effective ignition. This spark plug is compatible with a wide range of ignition systems, from simple coil and distributor setups to modern electronic and direct injection systems found in performance vehicles. The Brisk HOR17LGS is designed for tuned cars, unleaded fuel cars, racing engines, and alternative fuel cars. It features a patented firing tip design that does not require indexing or gapping, and it has a service life of 60,000 km or 40,000 miles, with a racing limit of 50 hours.
