NGK ILZKAR8H8S Laser Iridium Spark Plug – Stock No. 95112
This Laser Iridium plug delivers a strong, consistent spark with long service life. It handles high combustion temperatures well, making it a solid choice for modern turbocharged petrol engines that specify an NGK heat range 8 plug.
Use this plug to improve cold starts, smooth idle, and reliable performance under load. The fine iridium centre tip needs less voltage to fire, while the platinum ground pad helps it last longer than standard plugs.
- Strong spark and stable combustion for everyday and spirited driving
- Fine-wire iridium centre electrode for efficient ignition
- Durable platinum-tipped ground electrode for long life
- Resistor type for clean radio/ECU operation
