Perfect just as ordered

Truck driver!!! Do not buy this product its junk!!! I had to change the sensor twice and it cost me more than 1000$ please buy the part directly from dealership.

This part is specifically made for newer engine models like those in the Mercedes-Benz and Western Star trucks from 2016 to 2022. Installation was standard difficulty needing a few tools and a couple hours. I’m not a mechanic but after doing a couple of these before it's fairly easy in the grand scheme of auto work. The sensor fits perfectly and was easy to connect with everything matching the OEM. After installing it I noticed an immediate difference in my truck's performance. The engine seemed to run smoother and more efficiently plus dash light was gone. A NOx sensor helps reduce harmful emissions from the exhaust. It will help with inspection and knowing my truck is running properly. It meets OEM standards so I felt confident it would deliver good quality and reliability. Good experience.

I was having a NOX sensor code flashing at me, so I took a chance on this for my replacement, it shipped fast, and fit exactly like the OEM product, it immediately fixed my code.
