Denso original Common Rail Hydraulic Fuel Injector 095000-6170 095000-6171 8-98055863 Replacement for OEM 4JJ1 4JK1 Diesel Car Excavator Parts original new injector

The DENSO Common Rail Fuel Injector 095000-6170 is engineered as a direct OE-type replacement for the ISUZU 4JK1 and 4JK1-TC 2.5L diesel engine, fully matched to the original 8-98011605-0 fuel system specification. The electronic control unit drives precise high-pressure injection, delivering accurate fuel metering, fine atomization, and stable combustion across the full RPM range. This injector is built for ISUZU D-Max I 2.5 DiTD, D-Max 2.5 DiTD 4x4, D-Max 2.5 CRDi, and Rodeo 2.5 models, and is commonly used in pickup truck repair, light commercial vehicle maintenance, engine rebuild programs, and export spare parts distribution. Single-piece supply and full four-piece engine set supply are both available to support workshop and fleet demand.

Compatible cross numbers include 095000-6990, 095000-6991, 095000-6992, 8-98011605, 8-98011605-1, 8-98011605-2, 8-98011605-3, and 8-98055863-2, allowing flexible sourcing against multiple reference numbers within the same injector family. Strict quality control procedures cover dimension inspection, solenoid resistance testing, spray pattern verification, and full-poppet flow testing on the test bench, ensuring consistent performance before shipment. To prevent premature failure, operators should always use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and keep the fuel tank and lines free of contamination.

Before replacement, professional diagnosis is strongly recommended when symptoms such as hard starting, long cranking, black smoke, white smoke, rough idle, low power, high fuel consumption, rail pressure fluctuation, or injector correction imbalance appear. A complete diagnostic workflow should include return-flow testing, rail-pressure checking, cylinder balance analysis, electrical inspection, fuel contamination inspection, and test bench verification. Confirming the original OE number 095000-6170 or 8-98011605-0 prior to installation avoids unnecessary part replacement and reduces troubleshooting time in B2B service operations.
