Cummins SCR Filter : OEM 5418556

Engineered for Compliance: Cummins SCR Filter (OEM 5418556)

What is it?
The Cummins SCR Filter (OEM 5418556) is a Selective Catalytic Reduction (SCR) unit designed for modern Cummins heavy-duty engines, including ISX and QSX platforms. It plays a key role in reducing nitrogen oxides (NOₓ) emissions by converting them into harmless nitrogen and water vapor through precise Diesel Exhaust Fluid (DEF) dosing and catalytic reaction.

Why Choose the Cummins SCR Filter (OEM 5418556)?
This SCR module is built to Cummins’ factory specifications, ensuring accurate fitment, sensor compatibility, and long-term reliability. The geometry, materials, and internal catalyst structure match OEM standards, maintaining optimal exhaust flow and emission reduction efficiency. Choosing an OEM-spec filter minimizes installation errors, ensures system calibration accuracy, and supports consistent performance over the unit’s service life.

Key Benefits
✅ OEM-Level Compatibility: Matches original mounting flanges, sensors, and exhaust connections for seamless installation.
✅ Rugged Design: Constructed to withstand extreme heat, vibration, and exhaust pressures.
✅ Efficient NOₓ Reduction: Promotes complete catalytic conversion for cleaner exhaust output.
✅ Enhanced System Stability: Reduces aftertreatment fault codes and maintains smooth emission system operation.
✅ Protects Downstream Components: Cleaner exhaust minimizes strain on sensors, piping, and other emission control parts.

Applications
The Cummins SCR Filter (OEM 5418556) is suitable for heavy-duty trucks, industrial equipment, and commercial fleets using Cummins ISX, QSX, or compatible engines. It’s ideal for regional, long-haul, and high-load applications where emission compliance, durability, and reliability are top priorities.

Installation Notes
Professional installation is strongly recommended. Begin by verifying engine compatibility and part number accuracy. Remove the existing SCR filter carefully, inspecting all sensor ports, clamps, and gaskets for wear or corrosion. Clean all mounting surfaces and replace seals as needed. Install the new unit, ensuring all bolts are tightened to manufacturer torque specifications and that sensors and wiring are reconnected securely. Once installed, clear any diagnostic codes, run the engine through a full operating cycle, and monitor exhaust temperature and pressure to confirm proper functionality.

Final Thoughts
Modern emissions systems depend on precise, reliable components to function effectively. The Cummins SCR Filter (OEM 5418556) delivers a factory-accurate solution designed for longevity, proper fit, and efficient NOₓ reduction—helping your Cummins-powered vehicle stay compliant, efficient, and road-ready.
