Product Details

• Article Number: WK 5010 — Mann-Filter premium in-line fuel filter from the professional WK-series range. The "WK" prefix designates Mann-Filter's fuel filter product line ("Wasser-Kraftstoff" = water-fuel separator), engineered for high-performance fuel filtration with integrated water separation capability.
• Filter Type: In-Line Filter — installs in the fuel feed line between the fuel tank and the high-pressure fuel pump. Direct-fit replacement for the original BMW filter location.
• Height: 260 mm — overall filter length, dimensionally identical to the Ridex equivalent for direct fitment in the OEM bracket.
• Diameter: 55 mm — outer housing diameter.
• Outlet Diameter: 9 mm — fuel outlet port diameter (slightly larger than the Ridex 8 mm spec, but matches BMW's standard outlet line connection).
• EU Product Safety Regulation (GPSR): IEC 60417-6183 mechanical expertise required — indicates this is a technical component requiring qualified installation. Best installed during routine service by a competent mechanic.
• Function: Removes water, rust particles, dirt, and microscopic debris from fuel before it reaches the high-pressure fuel pump and injectors. The Mann-Filter WK-series uses multi-stage filtration media including a water-separation layer that coalesces water droplets out of the fuel — particularly important for diesel applications where water contamination is a leading cause of fuel system damage.
• Water Separation: Built into the filter element design — separates emulsified water from diesel fuel before it can reach and damage the high-pressure fuel pump and injectors. This feature is especially valuable in conditions where fuel quality cannot be guaranteed (small filling stations, older underground storage tanks, seasonal moisture issues).
• Condition: New — factory-sealed in Mann-Filter OE packaging.
• Manufacturer: MANN-FILTER (Mann+Hummel) — German OE supplier founded in 1941, headquartered in Ludwigsburg. Mann+Hummel supplies original-equipment fuel filters directly to BMW, Mercedes-Benz, Porsche, Audi, and Volkswagen factories — meaning this filter is functionally identical to a "Genuine BMW" fuel filter at a fraction of the dealer price.
• OEM Cross-References: BMW 13 32 7 823 411, BMW 13 32 7 823 413 (plus additional BMW cross-references) — direct equivalents to these original BMW part numbers. Notable that this Mann filter covers a BMW number (13 32 7 823 411) NOT shown on the Ridex equivalent — slightly broader OEM compatibility coverage.
• Vehicle Compatibility: Designed for the BMW X3 F25, particularly diesel variants including the sDrive 18d (N47 D20 C engine). Always verify against your vehicle's VIN or existing filter part number before purchasing.
• Quality Tier: Premium OEM-quality — Mann-Filter supplies BMW's factory fuel filters. Functionally identical to a "Genuine BMW" fuel filter, just without the BMW-branded packaging premium.
