NGK IFR7X8G Laser Iridium Spark Plug – Stock No. 95820
Built for reliable ignition under high load, the NGK IFR7X8G uses a fine iridium centre tip for a strong, stable spark. It withstands heat and pressure in turbocharged petrol engines, holding its gap for longer than standard plugs. Expect smooth cold starts, crisp throttle response, and consistent performance over a long service life. It will not add power on its own, but it helps your engine make the most of its tune and fuel when specified for your vehicle.
