NGK SILZKAR8G7Y Spark Plug – Stock No. 93710
A high-quality NGK Laser Iridium spark plug for modern petrol engines. The fine iridium tip needs less voltage to spark, so ignition stays strong under boost and high load. A platinum ground pad improves durability and keeps performance stable over a long service life.
This plug suits engines that use long-reach, small-diameter plugs common in many newer turbocharged petrol setups. For exact fitment, please use the vehicle lookup on our site or check the Vehicle Fitment tab.
- Sharper spark for cleaner combustion and smoother throttle response
- Cold heat range for reliable ignition in tuned or high-load conditions
Always follow your vehicle’s OE specifications for heat range, gap and installation torque.
