ADH22118 Blue Print Oil Filter

This Oil Filter from Blue Print (MPN: ADH22118) is a key element in the lubrication system of engines. It serves as a vital component for filtering engine oil to prevent contamination. The product is used in various vehicles, particularly those with Blue Print engines manufactured in China. Key technical benefits include improved engine longevity due to reduced wear on moving parts and enhanced overall vehicle reliability. Oil filters are cylindrical pressure-drop filters positioned in the engine’s oil lubrication system. They remove ferrous particles, dirt, and combustion byproducts from circulating oil, protecting critical engine components from wear. Filter media typically consists of pleated cellulose, synthetic blends, or full synthetic materials, varying in efficiency measured by micron rating. Construction includes a metal housing, internal bypass valve to maintain oil flow during blockage, and a threaded mounting boss compatible with vehicle-specific adapters. Anti-drainback valves prevent oil from flowing back into the sump when the engine is off, ensuring immediate lubrication upon startup. Filter capacity is rated in quarts or liters and dictates service intervals.
