NGK DILKAR8J9G Laser Iridium Spark Plug
This NGK Laser Iridium spark plug is built for clean, reliable ignition under high load. It uses a fine iridium centre electrode for a strong spark and a platinum pad on the ground electrode for long life. It helps cold starts, smooth idle, and stable performance in tuned or factory engines that specify this heat range and design.
Use this plug where an NGK heat range 8 with 0.9 mm gap and M12 long-reach fitment is required. For exact fitment, please use the vehicle lookup or check the Vehicle Fitment tab.
- Strong spark and stable combustion under boost and high temperatures
- Iridium centre and platinum ground for durability and consistent gap
- Resistor design to reduce electrical noise for the ECU and sensors
