High Quality Truck Part Dongfeng SHACMAN JAC SINOTRUK FAW Weichai Yuchai Engine Oil Filter element 1DQ000-1012011

The Yuchai Oil Filter (Part No. 1DQ000-1012011) is an OEM-manufactured spin-on full-flow oil filter designed specifically for use with Yuchai diesel engines, particularly in medium- and heavy-duty commercial vehicles, construction machinery, and industrial power units. As a critical component of the engine lubrication system, it ensures continuous removal of harmful contaminants such as soot, metal particles, sludge, and carbon deposits from circulating engine oil.

Featuring advanced filtration media, integrated safety valves, and robust construction, this filter delivers reliable protection under high-pressure conditions and extreme operating environments. It plays a vital role in extending engine life, reducing wear on internal components, and maintaining optimal oil pressure—especially during cold starts and prolonged operation.
