NGK SILFER8C7ES Spark Plug (Stock No. 94712)
This NGK Laser Iridium spark plug is built for stable ignition and long life. It uses a fine iridium centre electrode and a platinum-tipped ground electrode for strong sparks with less voltage. That helps cold starts, smoother idle, and reliable performance under boost. Heat range 8 suits many modern high-output petrol engines and tuned setups where extra knock resistance and cooler running at the plug are useful.
- Fine-wire iridium centre for a strong, consistent spark
- Platinum ground pad for long service life
- Resistor design to reduce electrical noise for the ECU

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.
