Built to original equipment form, fit and function, the NGK Spark Plug Set covers Hyundai Kona and Hyundai Tucson and Hyundai i30 2.0L Petrol models built from 2018 to 2020. The Iridium centre electrode is 5.0mm in diameter, which lowers the voltage needed to jump the gap and improves cold starting. A trivalent metal plating on the shell resists corrosion and seizing in aluminium heads. Ribbed insulator construction prevents flashover to the coil boot. New stock, 2 Years / 40,000 km warranty, and dispatched from our Australian warehouse.
