NGK ILZKR8C8G Laser Iridium Spark Plug – Stock No. 90909
This NGK Laser Iridium plug delivers reliable ignition under hard use. The fine wire iridium tip needs less voltage to spark, which helps cold starts and smooth idle. It also resists wear, so performance stays consistent for longer service intervals.
Heat range 8 is a colder grade than many OE plugs. This suits tuned or high-load engines where combustion temperatures are higher. For standard engines, follow the vehicle maker’s specification.
Use one plug per cylinder. Always install as per the vehicle service manual. Set gap only if the manufacturer specifies it for this exact plug.
- Ideal for modern petrol engines, including turbo applications where a colder heat range is specified
- Stable spark and strong knock resistance under boost and high RPM

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
