Cummins ISX15 SCR Filter 2011-2013: OEM 4329094

Emission-Ready Aftertreatment Component for Cummins ISX15 Engines (2011–2013)

What is it?
The Cummins ISX15 SCR Filter for model years 2011–2013, identified by OEM part number 4329094, is a selective catalytic reduction component designed to support the reduction of nitrogen oxides (NOx) in the exhaust stream. Working in conjunction with Diesel Exhaust Fluid (DEF), the SCR filter helps facilitate a chemical reaction that transforms NOx into nitrogen and water, assisting the engine’s emissions aftertreatment system in meeting regulatory requirements.

Why choose this SCR Filter?
This SCR filter is engineered to Cummins’ original specifications for the ISX15 engine platform, ensuring accurate fitment and proper integration with associated DEF dosing hardware, sensors, and control modules. When the SCR filter becomes restricted or less effective, NOx conversion efficiency can diminish and lead to system alerts or inconsistent emissions behavior. Using the correct OEM-specified SCR filter helps support dependable emissions control and coordinated aftertreatment system responses.

Key Benefits
✅ Designed specifically for Cummins ISX15 emissions systems (2011–2013)
✅ Helps support reliable NOx conversion via SCR chemistry
✅ Maintains coordinated operation with downstream emissions components
✅ Direct-fit replacement — no modifications required
✅ Built to handle the thermal demands of heavy-duty exhaust environments

Applications
This SCR filter is ideal for heavy-duty trucks and commercial vehicles equipped with Cummins ISX15 engines built between 2011 and 2013. It is especially suited for applications where adherence to emissions standards is essential, including long-haul, regional transport, and vocational duties.

Installation Notes
Before servicing, ensure the exhaust and aftertreatment system has fully cooled. Remove the existing SCR filter and inspect surrounding DEF lines, sensors, and mounting hardware for wear or contamination. Install the replacement SCR filter with proper seals and hardware to ensure secure alignment and minimal leakage. After installation, clear stored fault codes and verify correct emissions system behavior with appropriate diagnostic tools.

Final Thoughts
If your Cummins ISX15-equipped vehicle is showing NOx-related warnings or reduced emissions control effectiveness, replacing the SCR filter with the correct OEM-specified unit can help restore coordinated NOx reduction and dependable aftertreatment performance. The Cummins ISX15 SCR Filter (OEM 4329094) plays an important role in sustaining regulated exhaust chemistry and supporting consistent vehicle operation.
