Mann-Filter is the independent-aftermarket brand of MANN+HUMMEL, the Ludwigsburg-based filtration group founded in 1941. The parent supplies oil, air, fuel, and cabin filters as factory equipment to European automakers — Audi, BMW, Mercedes-Benz, Porsche, and Volkswagen among them — which means many Mann-Filter aftermarket part numbers share tooling and media specs with the corresponding OE filter rather than being a generic look-alike.
In the US aftermarket Mann-Filter is best known for European-fitment coverage where OE-grade replacement matters: cabin filters with activated carbon for German platforms (the CUK series), oil filters for VAG and BMW four- and six-cylinder engines, and engine air filters cross-referenced to OE part numbers. The brand publishes a vehicle-fitment lookup on mann-filter.com, and part numbers carry the OE-spec prefix convention (CU = cabin, CUK = cabin with activated charcoal, C = air, W = oil) consistent with the European supplier catalog.
