E428LS Air filter

Elongated cylindrical air filter element for MAN TGX and TGS platforms using a specific vertical or angled housing configuration — equivalent to MAN OEM 81084050017. The elongated format is used where the available installation space dictates a taller, narrower element rather than the wider round types fitted to other MAN models. Hengst filter media in the E428LS provides high dust-holding capacity and low initial restriction, both important for maintaining consistent turbocharger boost pressure across the full service interval. A blocked air filter causes measurably higher exhaust gas temperatures as the engine runs progressively lean at high load — sustained operation in this condition risks DPF overloading and catalyst damage. Always confirm the housing part number or compare the physical dimensions of the fitted element before ordering: similar-looking MPN formats can cover multiple internal sizes that are not mechanically interchangeable. Replace at the scheduled interval or immediately when the restriction indicator warning activates — do not continue operating with a restricted intake.
