NGK ILKAR7L11 Laser Iridium Spark Plug – Stock No. 94124
This NGK Laser Iridium plug delivers a strong, consistent spark. It helps cold starts, smooth idle, and stable performance under load. The fine iridium tip needs less voltage, which can reduce misfires and maintain efficiency over a long service life.
Use it as a quality maintenance replacement or when tuning for reliable ignition at higher boost or RPM. It is a long-reach M12 design commonly used in modern petrol engines.
- Fine iridium centre tip for reliable ignition and long life
- Platinum ground pad for stable gap over time
- Built-in resistor to reduce electrical noise (helps ECU sensors)
- Projected tip for good flame spread and response

Fitment guidance
Suitable for engines that specify an M12 long-reach (26.5 mm) plug with 1.1 mm gap and NGK heat range 7. Often found in selected modern Toyota and Lexus petrol engines. Use the site’s vehicle lookup to confirm, or check the Vehicle Fitment tab for full details.
Installation notes
Always follow the vehicle manufacturer’s torque and gap specifications. The plug is pre-gapped to 1.1 mm; avoid forcing the fine iridium tip. Typical torque for M12 gasket-seat plugs is 18-25 Nm, but refer to your workshop manual. Fit to a cold engine, apply a small amount of anti-seize only if the manufacturer allows it, and use a torque wrench for accuracy.
