Show original supplier description
The Brisk Premium LGS Racing DOR15LGS-T spark plug is engineered to deliver exceptional ignition performance in tuned and racing engines. Its distinctive multi-ground electrode design, combined with a silver center electrode, facilitates a 360-degree discharge, ensuring efficient ignition of rich mixtures. This design increases the ignition surface area and requires lower voltage levels for arcing. The silver center electrode is chosen for its superior thermal and electrical conductivity, allowing for faster heat dissipation and a more powerful spark. This leads to a quicker and more effective flame front. The multi-ground electrode design eliminates the need for a precise placement relative to the mixture, unlike single-electrode designs. Key specifications for this spark plug include a 14mm thread diameter, a 19mm (3/4 inch) thread reach, and a 16mm (5/8 inch) hexagon size. It features a gasket seat, a projected tip, and a resistor, with a heat range of 15. The DOR15LGS-T is designed for a service life of up to 60,000 km (40,000 miles) or 50 hours in racing conditions. It is also stated to replace the NGK BKR6E. This spark plug is compatible with a wide range of ignition systems, including simple coil and distributor setups, as well as electronic and direct ignition systems found in modern performance engines. It is recommended for tuned cars, unleaded fuel cars, racing engines, and alternative fuel cars. The patented firing tip design requires no indexing or gapping.
