FAQ

Q1: Are 5WK96672A and 2871974 the same sensor?
A1: Yes. 2871974 is the Cummins OE number, and 5WK96672A is the Continental/Bosch NOx sensor reference used in EPA10 SCR systems. (Dinex Product Sheet)

Q2: What vehicles use this sensor?
A2: It is commonly used on Cummins ISX/ISB engines installed in Kenworth, Peterbilt, Freightliner, and International trucks equipped with SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream or downstream NOx sensor depending on SCR layout and ECU configuration.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends data to the ECU, which adjusts AdBlue injection to reduce emissions and maintain SCR efficiency.
