E202H01D34 Hengst Oil filter

This Hengst oil filter (E202H01D34) serves as a vital part in the lubrication system, tasked with filtering out contaminants from engine oil. It is commonly used in passenger vehicles and commercial fleets. By utilizing this oil filter, users can expect improved engine performance, extended engine life, and enhanced fuel efficiency. 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.
