NGK IKR6G11 (Stock No. 7980) Laser Iridium Spark Plug
The NGK IKR6G11 is a high-quality Laser Iridium spark plug designed for clean ignition, strong performance, and long service life. It uses a fine iridium centre electrode for a stable spark and a platinum-tipped ground for durability. This helps cold starts, improves throttle response, and keeps emissions in check when the engine is under load.
Use it as a direct replacement where IKR6G11 is specified by the manufacturer. It suits many modern petrol engines that require an NGK heat range 6 iridium plug. Always confirm fitment with the vehicle lookup or check the Vehicle Fitment tab.
- Sharp, consistent spark for smooth idle and reliable starts
- Laser-welded iridium tip for long life and sustained performance
- Resistor design reduces electrical noise that can affect the ECU
- Pre-gapped to 1.1 mm – check and adjust only if your manufacturer specifies differently
