NGK SILKR7H8 Laser Iridium Spark Plug
This NGK Laser Iridium plug delivers strong, reliable ignition under load. The fine iridium tip needs less voltage to spark, so combustion is cleaner and more consistent. That helps throttle response, smoother idle, and stable performance at high rpm. The laser-welded precious metal pads resist wear, keeping the spark sharp over a long service life.
Built with an internal resistor to reduce radio noise and protect sensitive electronics (like the ECU). Pre-set gap for quick, accurate installation. Ideal for performance-tuned petrol engines that demand stable ignition and heat control.
- Sharper spark with low voltage demand for cleaner burn
- Durable precious-metal electrodes for long life
- Heat range chosen for balanced knock resistance and fouling control

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.
