This Hyundai Genuine Spark Plug Set replaces the original equipment unit on Hyundai i30 2.0L Petrol models built from 2020 to 2022. Service life of up to 100,000km is typical in normal conditions. A trivalent metal plating on the shell resists corrosion and seizing in aluminium heads. The Platinum centre electrode is 3.5mm in diameter, which lowers the voltage needed to jump the gap and improves cold starting. Ribbed insulator construction prevents flashover to the coil boot. 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. New stock, 24 Months warranty, and dispatched from our Australian warehouse.
