NGK ILZKAR7E11S Laser Iridium Spark Plug – Stock No. 96509
NGK’s ILZKAR7E11S is a long-life laser iridium spark plug designed for clean, reliable ignition. It uses a fine iridium tip and a platinum ground pad to keep the spark strong over high mileage. This helps cold starts, smooth idle, and consistent performance, even under load or light tuning.
The fine-wire centre electrode needs less voltage to fire. That reduces misfires and helps the ECU keep timing stable. A projected tip improves flame spread for better throttle response and fuel efficiency. The resistor design also cuts radio noise.
If you are upgrading or refreshing your ignition system, this plug is a dependable choice for modern petrol engines that specify an NGK heat range 7 iridium plug with a 1.1 mm gap.
- Good for daily driving and mild performance use
- Stable spark at high temperatures and RPM
- Long service life vs standard nickel plugs
