MAN Truck Filters Guide

MAN Trucks at a Glance

MAN Truck & Bus is one of Europe's major commercial vehicle manufacturers, headquartered in Munich, Germany, with industrial roots going back to 1758 and truck production since 1915. It is part of the TRATON GROUP. MAN trucks are widely used in long-haul transport, construction, distribution, and municipal work across Europe, the Middle East, Africa, Asia, and Latin America, and the brand is known for efficient in-line six-cylinder diesel engines.

Main MAN Truck Models

MAN TGX. The flagship long-haul tractor. The current generation, launched in 2020, was named International Truck of the Year 2021. Most TGX trucks in service use the D26 engine, which makes its filters the most commonly requested.

MAN TGS. The versatile model for distribution and construction, available in many axle and cab configurations. It shares many service parts with the TGX.

MAN TGM. A medium-duty truck for regional distribution, municipal work, and body-builder applications.

MAN TGL. A light-duty truck for urban delivery and short-distance work.

MAN TGA. The previous-generation range, still very common on roads in Europe and many export markets, so TGA filters remain in steady demand.

Common MAN Filter Part Numbers (D26 Engine, TGX and TGS)

The D26 engine (D2676) is the most widely serviced MAN engine. The references below are those commonly shown in aftermarket cross-reference catalogs.

MAN offers several fuel and oil filter variants by engine and emission level, so the same model can use different part numbers. Confirm using the engine code and chassis number.

MAN Filter Maintenance Guide

Fuel filters. MAN's high-pressure common-rail systems need clean fuel. Replace fuel filters on schedule, drain water from the separator regularly, and prime the system after each change to avoid air in the fuel lines.

Oil filters. Replace the oil filter at every oil change, using a filter that matches the original bypass valve and media specification. Low-quality filters can compromise turbocharger and bearing protection.

Air filters. Inspect the restriction indicator and the housing seals at every service. Trucks on construction or agricultural routes need much more frequent air filter replacement than highway tractors.

Cabin filters and air dryer. Replace the cabin filter at least once a year and the air dryer cartridge on schedule to protect the air brake system from moisture and oil.

Service intervals depend on the manufacturer's maintenance plan, engine variant, oil specification, and duty cycle. Always follow the plan for your specific vehicle.

How to Choose the Right Replacement Filter for a MAN

• Identify the engine code (such as D2066, D2676, or D3876) and the production date before searching for a number.
• Match the OE reference, then confirm dimensions, thread, and seal arrangement, since MAN uses both cartridge and spin-on designs.
• Verify that the replacement meets the original efficiency, flow, and bypass specifications, not just physical fit.
• For mixed fleets, work with a supplier that provides cross-references across MAN, Scania, Volvo, DAF, and Iveco.

Frequently Asked Questions

What fuel filter does a MAN TGX D26 use? Listings for D2676 engines in TGX and TGS trucks commonly reference MAN 51.12503-6004 (Mann PU 10 029 z), but earlier or variant engines may use different numbers, so verify by engine code.

Are MAN TGA and TGX filters the same? Some are, but not all. The TGA and TGX generations differ in emission level and filter housing design, so check the engine code and production date rather than assuming a match.

Can aftermarket filters be used on MAN trucks? Yes, if they meet or exceed the original specification for efficiency, flow, and pressure rating and come from a manufacturer able to supply test data.

For fleets and distributors sourcing replacement filters for MAN trucks, ADAOER Filter manufactures heavy-duty fuel, oil, air, cabin, and hydraulic filters for trucks, buses, and construction machinery, and supports OEM/ODM development for custom specifications. Cross-reference lists are available on request.

Brand names and part numbers are used for identification and compatibility reference only. MAN, Renault Trucks, and Iveco are trademarks of their respective owners. Part numbers vary by chassis, engine variant, emission level, and production date, so always verify the correct filter against your vehicle's VIN or chassis number and engine code before ordering.
