International Navistar A26 DPF Filter 2021-2024: OEM 2522144C1

Purpose-Built Particulate Management for International/Navistar A26 Engines (2021–2024)

What is it?
The International Navistar A26 DPF (Diesel Particulate Filter) for 2021–2024 applications, identified by OEM part number 2522144C1, is a primary exhaust aftertreatment component. It traps and holds particulate matter (soot) from the engine’s exhaust stream, working with the vehicle’s regeneration strategy to periodically burn off accumulated residue and help maintain consistent exhaust behavior.

Why choose this DPF Filter?
This DPF is engineered specifically for the International/Navistar A26 platform to match original equipment specifications, ensuring correct alignment with exhaust sensors, mounts, and regeneration controls. Over time, particulate filters can become restricted or lose effectiveness, which may increase exhaust back-pressure and trigger system warnings. Installing the proper OEM-specified filter helps support stable exhaust movement and more predictable regeneration cycles.

Key Benefits
✅ Designed to meet International/Navistar A26 aftertreatment requirements
✅ Captures soot and other particulate matter
✅ Helps sustain reliable exhaust flow
✅ Direct-fit replacement — no modification needed
✅ Built to tolerate heavy-duty exhaust conditions

Applications
This DPF filter is ideal for heavy-duty trucks and commercial equipment powered by International/Navistar A26 engines manufactured between 2021 and 2024. It’s well suited for freight haulers, regional transport units, vocational vehicles, and other duty cycles where consistent particulate capture and controlled regeneration are essential to keep vehicles in service.

Installation Notes
Before servicing, make sure the exhaust and aftertreatment system has fully cooled. Carefully remove the existing DPF filter and inspect adjacent exhaust piping, mounts, and sensors for soot buildup or damage. Install the new filter with proper clamps, gaskets, and seals to ensure a secure fit. After installation, clear any stored system codes and verify correct aftertreatment operation using diagnostic tools.

Final Thoughts
If your International/Navistar A26-equipped vehicle exhibits restricted exhaust flow, frequent particulate warnings, or uneven regeneration behavior, replacing the DPF with the correct OEM-specified unit can help restore balanced soot management and steadier system performance. The International Navistar A26 DPF Filter (OEM 2522144C1) plays an important role in maintaining emissions system stability and dependable operation.
