Direct-Fit OEM Replacement: Engineered to match factory specifications with original-style connector and harness length for easy installation.
Improves Engine Efficiency: Provides real-time NOx data to the ECU, enhancing combustion control and DEF management.
Durable & Heat Resistant: Built from high-temperature stainless steel with sealed electronics to withstand harsh exhaust conditions.
Plug-and-Play Design: Installs in minutes with no modifications or programming required.
Interchange Part Number: 68067521AA
Compatible Vehicle Applications (U.S./Canada Models):
For 2011–2012 Ram 2500 6.7L Cummins Diesel
For 2011–2012 Ram 3500 6.7L Cummins Diesel
For 2011–2012 Ram 4500 6.7L Cummins Diesel
For 2011–2012 Ram 5500 6.7L Cummins Diesel
Note: This is the upstream (before SCR) NOx sensor mounted before the catalytic reduction system. For the downstream sensor, see part number 5149216AB.
