NGK SILZNAR6D9 Laser Iridium Spark Plug (Stock No. 94051)
The NGK SILZNAR6D9 is a high-quality Laser Iridium spark plug designed for stable ignition and long service life. It delivers a strong, consistent spark, helping engines start cleanly, idle smoothly, and perform reliably under load. The fine iridium centre electrode reduces the voltage needed to fire, while a platinum-tipped ground electrode helps maintain performance over time.
This plug suits many modern petrol engines that specify NGK Laser Iridium with heat range 6 and a 0.9 mm gap. Always confirm fitment using the vehicle lookup or the Vehicle Fitment tab.
- Fine-wire iridium tip for reliable ignition and smoother throttle response.
- Platinum ground pad for long life and consistent performance.
- Built-in resistor to reduce electrical noise that can affect sensors and audio.

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.
