Cummins X15 NOx Sensor 2022-2024: OEM 5679700
Strengthen Exhaust Emissions Performance with an SCR Outlet Catalyst Module for Cummins ISX15 Engines
What is it?
The Cummins ISX15 SCR outlet catalyst module, identified by OEM 5313988, is an emissions aftertreatment component designed for Cummins ISX15 engines produced between 2014 and 2018. Located at the outlet side of the Selective Catalytic Reduction (SCR) system, this module helps complete the exhaust treatment process by reducing nitrogen oxide (NOx) emissions before exhaust gases exit the vehicle.
Why choose this SCR Outlet Catalyst Module?
Heavy-duty diesel engines rely on properly functioning catalyst modules to maintain emissions compliance and efficient aftertreatment operation. This SCR outlet catalyst module is manufactured to match Cummins ISX15 specifications, ensuring compatibility with factory-installed DEF dosing systems, sensors, and exhaust components. Over time, catalyst materials can become less effective due to soot accumulation, contamination, and continuous exposure to extreme exhaust temperatures. Replacing the module with the correct OEM-matched component helps maintain consistent emissions processing and stable exhaust flow.
Key Benefits
✅ Designed for Cummins ISX15 engines (2014–2018)
✅ Supports effective NOx reduction through the SCR process
✅ Helps maintain dependable aftertreatment system performance
✅ Direct-fit replacement for proper installation
✅ Built to withstand demanding high-temperature exhaust conditions
Applications
This SCR outlet catalyst module is used on heavy-duty trucks and commercial vehicles equipped with Cummins ISX15 engines from 2014 through 2018. Common applications include long-haul tractors, regional freight trucks, vocational vehicles, and fleet equipment where reliable emissions control and aftertreatment performance are essential.
Installation Notes
Before installation, allow the exhaust and aftertreatment system to cool completely. Remove the existing catalyst module and inspect surrounding DEF components, sensors, clamps, and exhaust connections for signs of wear or contamination. Install the replacement module using the appropriate mounting hardware and sealing components to ensure correct alignment and leak-free operation. After installation, verify proper aftertreatment functionality and clear any stored fault codes using diagnostic equipment.
Final Thoughts
If your Cummins ISX15-powered vehicle is experiencing emissions warnings, reduced SCR efficiency, or inconsistent aftertreatment performance, replacing the SCR outlet catalyst module with the correct OEM component can help maintain proper system operation. The Cummins ISX15 SCR outlet catalyst module (OEM 5313988) plays an important role in supporting dependable emissions control, efficient exhaust treatment, and reliable vehicle performance.
