Cummins NOx Sensor (5295473, 5295473RX) - Nitrogen Oxygen Outlet Sensor, Front Mount

This is a remanufactured NOx sensor for Cummins engines.

It's the nitrogen oxygen sensor that monitors exhaust gases.

The part numbers are 5295473 and 5295473RX, and it's also known as a 5WK9 6742B.

It's a direct-fit, easy-to-install sensor that goes on the front of the engine or exhaust system.

It's been completely rebuilt to function like new.

If you're getting engine codes related to emissions or NOx levels, swapping this sensor out might clear them up and get your truck running right again.
