Built to original equipment form, fit and function, the Donaldson Air Filter covers Nissan X-Trail 2.5L Petrol models built from 2015 to 2025. The frame is fully sealed at the corners to stop unfiltered air bypassing the element. Panel dimensions are approximately 350mm x 240mm, with a moulded polyurethane frame that seals hard against the airbox. Restriction is measured at under 125kPa at rated engine airflow. Service life of around 20,000km applies in normal conditions; halve that for dusty and rural use. The Cellulose media traps fine dust without choking airflow, which matters on Australian gravel and unsealed roads. Fitting is a straightforward workshop job and no coding or calibration is needed. Packaging and labelling include the part number and application data for easy stock control. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. New stock, 12 Months warranty, and dispatched from our Australian warehouse.
