4326873 Genuine Cummins Nox Nitrogen Oxide Sensor

So happy to have a source for American made parts, especially as I have tried all price ranges of dealer parts and foreign parts with no luck. So far my truck is behaving itself and no further engine check lights for the dreaded P2201 nox ckt error. Changing this out also removed the permanent P2201 error. I ordered the part from home and had it deliver to my campsite. 3-1/2 hours later it was installed. Thank you!
