Overview – DIRECT MOUNT AIR SYSTE AF25745 Series
The Cummins DIRECT MOUNT AIR SYSTE AF25745 is part of a proven family of components used across Cummins engine air intake as the direct-mount air filter, and several interchangeable part numbers share the same fitment.
Parts Characteristics
A direct-mount air filter that cleans the intake air at the engine, catching the abrasive dust that would otherwise score the turbo and the cylinders. It is the first defence of the whole air path, so a correct, sealing element keeps the engine from breathing grit.
Applicable Models & Applications
Fitted to Cummins engines specifying this direct-mount air system/filter. Match the flange, element size and seal against your old filter – air filters differ in how they seat and flow.
Maintenance & Replacement
Replace the element on the duty-adjusted interval, not only when the restriction alarm trips. A filter run past its limit sheds its media, and the grit goes straight into the turbo.
Confirm the seal seats fully and the housing is clean on fit. A filter that bypasses – through a rolled seal or a dirty face – lets dust past and the engine pays for it.
Pre-clean the intake path before fitting a new element. A housing serviced on residue re-contaminates the new filter within hours.
Keep the correct direct-mount air filters for your engine on the bench. They are consumable at every service, and an engine open on a filter is an engine waiting on a part.
Price Reference (USD)
