Cummins X15 SCR Filter 2022-2026: OEM 5418600

Balanced NOx Conditioning for Cummins X15 Engines (2022–2026)

What is it?
The Cummins X15 SCR Filter (2022–2026), with OEM part number 5418600, is an emissions aftertreatment component designed for Cummins X15 diesel engines manufactured from 2022 through 2026. This filter is part of the selective catalytic reduction (SCR) system, helping condition the exhaust stream as it moves toward the SCR catalyst, where nitrogen oxides (NOx) are chemically converted into nitrogen and water with the help of Diesel Exhaust Fluid (DEF).

Why choose this SCR Filter?
This SCR filter is engineered to Cummins’ original specifications for the X15 platform, ensuring a precise fit and reliable interaction with DEF delivery components, sensors, and the rest of the aftertreatment system. When the SCR filter becomes clogged or degraded, exhaust flow and NOx handling can become inconsistent, potentially leading to emissions warnings or uneven aftertreatment behavior. Choosing the correct OEM-specified filter supports stable emissions conditioning and more predictable system performance.

Key Benefits
✅ Designed to fit Cummins X15 aftertreatment systems (2022–2026)
✅ Helps prepare exhaust gases for effective NOx conversion
✅ Supports smoother interaction with DEF dosing and emissions sensors
✅ Direct replacement — no modifications required
✅ Built for demanding, heavy-duty exhaust conditions

Applications
This SCR filter is ideal for heavy-duty trucks and commercial vehicles powered by Cummins X15 engines manufactured between 2022 and 2026. It’s commonly used in long-haul tractors, regional transport rigs, vocational trucks, and other work vehicles where dependable emissions control and regulated exhaust handling are key operational needs.

Installation Notes
Before servicing, make sure the exhaust and aftertreatment system has fully cooled to avoid burns and component damage. Remove the existing SCR filter and inspect adjacent DEF lines, sensors, and mounting hardware for wear or soot buildup. Install the new filter using proper seals and clamps to ensure a secure, leak-free fit. After installation, clear any stored fault codes and verify correct aftertreatment behavior using diagnostic tools.

Final Thoughts
If your Cummins X15-equipped vehicle is experiencing NOx-related warnings, uneven emissions behavior, or inconsistent aftertreatment performance, replacing the SCR filter with the correct OEM-specified unit can help restore balanced exhaust conditioning. The Cummins X15 SCR Filter (OEM 5418600) plays a crucial role in supporting dependable NOx handling and emissions system stability across varied duty cycles.
