Useful Information

Description and Purpose:

This OEM DEF Doser Injector plays a critical role in reducing nitrogen oxide emissions by injecting precise amounts of urea into the exhaust stream. It is designed to work seamlessly with the SCR system found in Isuzu commercial vehicles including NPR-HD, NPR-XD, FTR, NQR, and NRR from 2011 to 2025, all equipped with Cummins diesel engines. Part Number: 8-98185-743-1. Brand: Isuzu. Condition: New. Cross reference: 8-98185-743-0, 8-98185-743-2, 98185743.

Why Replacement is Important:

Over time, DEF injectors may clog or fail due to crystallized fluid or contamination, leading to error codes, poor emissions performance, or vehicle derate. Timely replacement is essential to avoid downtime and prevent broader SCR system damage.

Impact on Vehicle Performance:

A properly functioning DEF injector improves emissions compliance, avoids check-engine lights, and maintains steady engine output. It also contributes to better fuel economy and ensures that the SCR system operates at full efficiency under load.

Manufacturer Information:

Isuzu® combines precision engineering and fuel efficiency, building vehicles that perform reliably across industries.
