NGK ILZKAR8J8SY Laser Iridium Spark Plug – Stock No. 95660
The NGK ILZKAR8J8SY is a high-performance Laser Iridium spark plug designed for modern turbocharged, direct-injection petrol engines. It delivers a strong, clean spark for reliable ignition under high load and high boost. The fine iridium centre electrode needs less voltage to fire, which helps start-up, idle quality, and throttle response. A platinum-tipped ground electrode improves durability and keeps performance stable over time.
