NGK SILZKR7C11S Laser Iridium Spark Plug
This NGK Laser Iridium spark plug delivers reliable ignition and stable performance. It uses a fine iridium centre electrode for a strong spark and long service life. A small platinum pad on the ground electrode helps keep the gap stable over time.
It suits many modern petrol engines that specify an NGK heat range 7 Laser Iridium plug with a 1.1 mm gap. Use the vehicle lookup to confirm exact fitment, or check the Vehicle Fitment tab.
- Strong cold starts and smooth idle
- Consistent spark under load for tuned or standard engines
- Long service life with minimal gap wear
