Key official cross-reference databases: Donaldson Filter Lookup (donaldson.com), Fleetguard CATALOG (fleetguard.com), Baldwin Filter Cross Reference, Wix Filter Lookup, Mann-Filter Product Finder. For Common Rail engine fuel filters, the critical parameter is the beta filtration ratio: β4 ≥200 means that of 200 particles of 4 µm size, only 1 passes through. Lower β ratings are dangerous for Bosch CP4 pumps — they destroy them within 200 engine hours. Ukrainian distributors with cross-reference databases: AgroRosa, OilTechProm, Filter-Service, TruckParts. When buying aftermarket filters always verify the β ratio and efficiency rating. Quality aftermarket filter (Donaldson/Baldwin/Fleetguard) price is 40–60% of OEM with 80–95% service life.
