FAQ

Q1: Is 5WK96722 the same as 51.15408-0008?
A1: Yes. 51.15408-0008 is the OE number and 5WK96722 is the Continental/Vitesco sensor reference used in the same NOx sensor family.

Q2: Is this inlet or outlet sensor?
A2: It can be used depending on SCR layout. This sensor family is commonly used across both positions with different harness lengths.

Q3: What vehicles does it fit?
A3: It is widely used in ISUZU SCR-equipped trucks, but exact compatibility depends on engine type (4HK1 / 4JJ1) and emissions calibration.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) in exhaust gases and helps the ECU control AdBlue dosing for emissions compliance.
