Built to original equipment form, fit and function, the Denso Spark Plug Set covers Hyundai Kona 2.0L Petrol models built from 2018 to 2024. Ribbed insulator construction prevents flashover to the coil boot. A trivalent metal plating on the shell resists corrosion and seizing in aluminium heads. Factory gap is set at 1.1mm and heat range 6 matches the original equipment specification. Replacing plugs as a full set keeps cylinder-to-cylinder combustion even and prevents misfire codes. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Every unit is supplied new with a 36 Months warranty against manufacturing defect.
