NGK ILZKAR7A10 Laser Iridium Spark Plug
The NGK ILZKAR7A10 is a Laser Iridium spark plug built for clean ignition, strong spark, and long life. It uses a fine iridium centre electrode and a platinum pad on the ground electrode. This helps cold starts, throttle response, and stability at higher RPM, while resisting wear in tuned or hard-driven engines.
It suits many modern petrol engines that require a 1.0 mm plug gap and a heat range 7. Always confirm fitment with the vehicle lookup or check the Vehicle Fitment tab.
- Fine-wire iridium centre for reliable ignition and smoother idle
- Platinum ground pad for stable performance over a long service life
- Resistor design to reduce electrical noise that can affect the ECU
