CUMMINS NOX SENSOR OEM# 4326867

Aftermarket Quality You Can Trust!

Our line of NOx sensors utilize Pulse Width Modulation (PWM) technology to heat them. Using a short burst rather than a continuous current as a heating source helps prolong the life of the ceramic chip and improves the sensor's accuracy. 

The probe cap has been designed to reduce contamination and effectively distribute flow around the probe.

The NOx sensor has been designed with enhanced programming to accommodate updates made by the OEM.

Aftermarket NOx sensors from American Radiator are direct replacements for OEM sensors and are matched by OEM number. Please confirm OEM cross to ensure proper fit and performance.

All sensors are brand new and not remanufactured.  That means No Core Charge for you!
