NGK DILZKAR7B11 Laser Iridium Spark Plug – Stock No. 90935
This NGK Laser Iridium spark plug delivers a strong, consistent spark for clean combustion and reliable performance. It uses a fine iridium centre tip with a precious-metal pad on the ground strap to reduce wear and maintain the correct gap for longer. The result is smoother idle, stable power under load, and dependable cold starts.
It is a heat range 7 plug (NGK scale), suitable for many modern engines that specify a long-reach M12 plug with a 1.1 mm factory gap. It is commonly used across popular Nissan and Infiniti V6 applications. Use our vehicle lookup or check the Vehicle Fitment tab to confirm compatibility.
- Durable precious-metal design helps the gap stay stable over high mileage
- Strong ignition under boost or high load for consistent performance
- Resistor design reduces electrical noise for sensitive ECUs
