Denso original 095000-5345 Common Rail Injectors for Truck Parts Diesel Fuel Injector Assembly 8-97602485-7 8976024857 Replacement for OEM original new injector

The DENSO 095000-5345 is an electronically controlled high-pressure common rail fuel injector designed for ISUZU 4HK1 common rail diesel engines and, in certain configurations, related 6HK1 applications. Built to original equipment standards, it receives pressurized diesel from the common rail and uses ECU signals to regulate precise injection timing and quantity. When energized, the internal control valve opens, the nozzle needle lifts, and fuel is atomized into a fine mist inside the combustion chamber, supporting stable combustion, efficient fuel economy, consistent power output, and controlled emissions across demanding commercial duty cycles.

This injector is widely fitted to ISUZU NQR75, NPR75, 700P, and other N-Series trucks equipped with the 4.0L–5.2L range 4HK1 powerplant. Some catalog references also list compatibility with ISUZU Forward, Bogdan, NQR71, and selected 6HK1 applications; however, 6HK1 fitment must be verified using the injector part number together with the engine serial number prior to purchase. A complete engine set typically requires four injectors for the 4-cylinder 4HK1 and six injectors for the 6-cylinder 6HK1 configuration. Cross references within the authorized OE list include 095000-5345, 095000-5340, 095000-5347, 095000-5344, and 8-97602485-7.

For reliable operation, keep the fuel system free of contamination, replace the fuel filter on schedule, drain the water separator regularly, and avoid poor-quality diesel. Before installation, confirm the part number, clean the injector bore, and always fit a new sealing washer instead of reusing old copper washers. After installation, perform ECU coding or injector learning when required, then inspect for leakage, abnormal noise, irregular smoke, and diagnostic trouble codes. If one injector fails due to contaminated fuel, inspect the entire fuel system; replacing a single unit without addressing the contamination will likely cause repeated failures.
