Built to original equipment form, fit and function, the Donaldson Fuel Filter covers Nissan X-Trail 2.5L Petrol models built from 2017 to 2019. Filtration is rated at 20 micron absolute to suit modern high-pressure diesel injectors. Replacement every 40,000km is cheap insurance against injector and pump damage. All seals and O-rings needed for the change are included in the box. The element withstands system pressure well above the factory lift pump output. Water separation efficiency exceeds 95 percent, which is critical protection for common-rail injection equipment. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Every unit is supplied new with a 2 Years / 40,000 km warranty against manufacturing defect.
