Diesel engines today rely on advanced emissions control systems to reduce harmful exhaust pollutants, and the Cummins B6.7 SCR Filter (2019–2021, OEM 5418487) plays a central role in that process. The Selective Catalytic Reduction (SCR) filter works with Diesel Exhaust Fluid (DEF) to convert nitrogen oxides (NOx) into harmless nitrogen and water vapor. Using the correct OEM-grade SCR filter ensures your engine’s emissions system functions efficiently and reliably, helping maintain compliance and optimal performance.
This SCR filter contributes significantly to cleaner emissions — here’s why it matters:
-
Reduces Harmful Emissions – Helps transform NOx gases into environmentally safe components, improving overall exhaust quality.
-
Supports Emissions Compliance – Installing the proper SCR filter helps ensure your engine continues to meet regulatory standards without triggering fault codes or performance restrictions.
-
Enhances System Efficiency – Proper filtering helps the SCR system operate effectively, minimizing backpressure and maintaining smooth exhaust flow.
-
OEM-Grade Fit and Durability – As OEM 5418487, this SCR filter matches original manufacturer specifications for size, materials, and performance, ensuring long-lasting reliability.
-
Prevents Emissions-Related Issues – Replacing a worn or clogged SCR filter helps avoid issues like increased fuel use, exhaust restrictions, or engine derate conditions.
A failing or restricted SCR filter can lead to reduced emissions performance, higher exhaust temperatures, or system warnings. The Cummins B6.7 SCR Filter (OEM 5418487) provides the OEM-standard quality and emissions control support needed to help your engine run cleaner and more efficiently.
