Description

The NGK Laser Iridium 91725 (LTR6BI-13) spark plug is engineered for peak engine performance and extended longevity. It features a precision laser-welded fine-wire iridium alloy center-electrode tip and a platinum ground electrode, maximizing horsepower and torque. Designed for the performance enthusiast, this spark plug offers a lifespan of 80,000 to 100,000 miles and delivers superior acceleration and ignitability. Its high-grade alumina silicate ceramic insulator resists dielectric punch-through. While pre-gapped for general use, proper gapping for specific applications is required. This plug serves as a direct replacement for various OEM part numbers, including Nissan B2401-HA00A and B2401-HA00D.
