Designed for commercial trucks such as the FTR, NPR-HD, NPR-XD, NQR, and NRR (2011–2025) equipped with Cummins engines, it delivers precise amounts of diesel exhaust fluid into the SCR system to reduce NOx emissions.

Why Replacement is Important:

A faulty DEF injector can lead to improper dosing, triggering warning lights, fault codes, and vehicle derating. Replacing the injector ensures accurate DEF delivery, restoring normal operation and preventing costly downtime or emissions violations.

Impact on Vehicle Performance:

A properly functioning DEF doser injector supports clean combustion by enabling the SCR system to neutralize harmful exhaust gases. It contributes to consistent power delivery, efficient fuel usage, and extended emission system life in heavy-duty applications.
