NGK ILNAR8B7G Laser Iridium Spark Plug – 91970
The NGK ILNAR8B7G is a high-quality Laser Iridium spark plug built for reliable ignition under load. It improves cold starts, resists fouling, and maintains a strong spark for longer than standard plugs.
Iridium needs less voltage to fire. This helps keep the spark stable at high RPM and under boost. The ground electrode uses a platinum pad to slow wear and keep performance consistent over time.
Use this plug when the vehicle manufacturer or your tuner specifies it. It is designed for modern petrol engines, including many turbocharged direct-injection units. Always confirm fitment with the site’s vehicle lookup, or check the Vehicle Fitment tab.
Why choose this plug
- Laser Iridium centre tip for strong, efficient ignition
- Platinum-tipped ground electrode for long service life
- Resistor design to reduce electrical noise and protect ECU systems
- Stable spark under boost and high cylinder pressures

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.
