The Denso Spark Plug Set is a direct-fit replacement for Mitsubishi Outlander 2.4L Petrol models built from 2016 to 2021. The Iridium centre electrode is 0.6mm in diameter, which lowers the voltage needed to jump the gap and improves cold starting. Replacing plugs as a full set keeps cylinder-to-cylinder combustion even and prevents misfire codes. Service life of up to 60,000km is typical in normal conditions. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Fitting is a straightforward workshop job and no coding or calibration is needed. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Packaging and labelling include the part number and application data for easy stock control. Sold new with 24 Months warranty cover and full technical support.
