2013-2018 Cummins 11.9L 15L ISX15 NOX Nitrogen Oxide Sensor Inlet 4326870 5WK96740B

Good quality, works as expected. Great replacement that saved me from a costly shop visit!

After installation, I needed help with the ECU reset procedure. Customer service emailed detailed instructions with clear photos. My car now runs perfectly smooth.

Very quick delivery! The package was sealed tightly and the part inside is exactly as ordered. No complaints at all.

Reliable performance in all conditions. The unit feels substantial in hand.

Plug and play perfection for my SC400. Immediate improvement in idle quality and fuel efficiency. Surprised by the quality!
