Product Details

• Article Number: C 36 014 — Mann-Filter premium engine air filter from the professional C-series range. The "C" prefix designates Mann-Filter's flat-panel OE air filter line, used as original equipment across German automotive platforms. The shaped contour visible in the product image confirms this is a custom-fit filter designed precisely for the BMW airbox geometry — not a generic rectangular panel.
• Filter Type: Filter Insert (panel-style with custom contoured shape) — drops directly into the BMW F25 airbox. No modifications or adapters required. Reinforced polyurethane frame ensures long-term dimensional stability, preventing airflow leaks that can occur with cheaper filters.
• Length: 348 mm — one of the main outer dimensions. Matches the factory airbox cavity precisely.
• Width: 270 mm — the shorter outer dimension. Combined with length, ensures the filter completely seals the airbox opening and prevents unfiltered air bypass.
• Height: 92 mm — depth profile of the BMW X3 F25 airbox. The substantial height provides a large effective filtration surface area through the deep pleats, ensuring extended service life.
• 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 dust, pollen, road debris, and fine particulate matter from intake air before it enters the engine. A clean filter maintains the correct air-to-fuel ratio, protects the mass airflow sensor, and preserves turbocharger and engine longevity. A blocked filter restricts airflow, causing power loss, increased fuel consumption, and accelerated wear on intake-system components.
• Condition: New — factory-sealed in Mann-Filter OE packaging.
• Manufacturer: MANN-FILTER (Mann+Hummel) — German OE supplier founded in 1941, headquartered in Ludwigsburg. Considered one of the top 3 filter manufacturers globally. Mann+Hummel supplies original-equipment filters directly to BMW, Mercedes-Benz, Porsche, Audi, and Volkswagen factories — meaning this filter is functionally identical to a "Genuine BMW" air filter, just without the BMW-branded packaging premium.
• OEM Cross-References: BMW 13 71 7 811 026 — direct equivalent to this original BMW air filter part number.
• Vehicle Compatibility: Designed for the BMW X3 F25. Always verify against your vehicle's VIN or existing filter part number before purchasing — BMW used different airbox sizes across different engine variants in the F25 platform. The C 36 014 matches the specific airbox geometry for variants requiring the 348×270×92 mm filter (likely the diesel variants, including the sDrive 18d).
• Quality Tier: Premium OEM-quality — Mann-Filter supplies BMW's factory air filters. Functionally identical to a "Genuine BMW" air filter at a fraction of the cost.
• Service Interval: BMW recommends replacement every 30,000–40,000 km or every 2 years under European driving conditions. For Tanzanian driving conditions (dusty roads, seasonal Harmattan dust, frequent dirt-road exposure), consider shortening the interval to every 15,000–20,000 km. A clogged filter in dusty environments can quickly cause turbocharger and MAF sensor damage that costs many times more than the filter itself.
• Inspection Tip: Hold the filter up to a strong light during routine services — if light barely passes through the pleats, the filter is overdue for replacement regardless of mileage.
