NGK DILKAR8A8 Laser Iridium Spark Plug (Stock No. 93026)
This high-performance spark plug uses a fine-wire iridium centre electrode and an iridium-tipped ground electrode. It gives a strong, clean spark under high pressure, which helps cold starts, throttle response, and stability at higher boost. The double-iridium design resists wear, so gap growth is slower and performance stays consistent for longer service intervals.
It suits many modern direct-injection petrol engines that specify an NGK heat range 8 plug with a 12 mm thread. Always confirm fitment with the vehicle lookup or see the Vehicle Fitment tab.
