Cummins X15 SCR 2022-2024: OEM 5418505

Tailored NOx Reduction Solution for Cummins X15 Engines (2022–2024)

What is it?
The Cummins X15 SCR (Selective Catalytic Reduction) module for 2022–2024 engines, with OEM part number 5418505, is a dedicated aftertreatment component designed to reduce oxides of nitrogen (NOx) in the exhaust. By working with Diesel Exhaust Fluid (DEF), the SCR unit triggers a chemical reaction that converts NOx into nitrogen and water vapor before the exhaust exits the system—helping meet strict emissions criteria.

Why choose this SCR Assembly?
This SCR unit is engineered to Cummins’ original specifications for the X15 engine series, ensuring accurate fitment and compatibility with onboard sensors, DEF injection systems, and control modules. If the SCR becomes compromised—due to age, contamination, or component failure—NOx reduction efficiency may decrease and trigger system warnings. Selecting the correct OEM-specified SCR helps retain dependable emissions control across diverse operating conditions.

Key Benefits
✅ Built specifically for 2022–2024 Cummins X15 aftertreatment systems
✅ Facilitates reliable reduction of NOx compounds in exhaust gases
✅ Supports stable coordination with other aftertreatment components
✅ Direct-fit replacement with no adjustments required
✅ Constructed to endure heavy-duty exhaust environments

Applications
This SCR assembly is ideal for heavy-duty trucks and commercial vehicles equipped with Cummins X15 engines produced from 2022 to 2024. It suits long-haul operations, regional freight carriers, vocational fleets, and other applications where precise emissions control and regulatory compliance are priorities.

Installation Notes
Before servicing, ensure the exhaust and aftertreatment system is fully cooled. Remove the existing SCR unit and inspect surrounding sensors, DEF lines, harnesses, and mounting hardware for wear or contamination. Install the replacement SCR assembly with proper seals and fasteners to ensure secure alignment. After installation, clear any stored codes and verify correct system responses using diagnostic tools.

Final Thoughts
If your Cummins X15-equipped vehicle is showing emissions system alerts or uneven NOx control behavior, replacing the SCR assembly with the correct OEM-specified unit can help restore coordinated emissions management. The Cummins X15 SCR (OEM 5418505) plays a central role in maintaining regulated exhaust chemistry and supporting dependable vehicle performance.
