The Injection Nozzle Assembly with OEM reference numbers 8-98011604-4 and 095000-6980 is a verified direct-fit replacement for the Isuzu 4JJ1 3.0L turbo-diesel engine. Manufactured by Denso, a global leader in automotive fuel systems, this injector is a precision component of the common rail fuel injection system, responsible for atomizing and precisely metering diesel fuel into the combustion chamber under extreme rail pressure.
Common rail injectors receive fuel from the common rail, which serves as a high-pressure fuel reservoir controlled by a mechanical or electronically controlled limiter. This injector delivers the precise fuel quantity and spray pattern required for optimal combustion, ensuring maximum power output, fuel efficiency, and emissions compliance.
A worn, leaking, or out-of-spec injector is a common cause of rough running, excessive smoke, hard starting, and poor fuel economy on 4JJ1 engines. This OE-spec replacement injector restores factory fuel delivery and engine performance.

Important Installation Information
⚠️ IMPORTANT: Fuel injector replacement requires mechanical competence and specialized diagnostic equipment. Professional installation strongly recommended.
Critical Requirements:
Injector coding / calibration is mandatory after installation. Common rail injectors must be coded to each cylinder using a professional diagnostic scan tool (e.g., Tech 2, G-Scan, or equivalent)
A new injector nozzle and body washer should be installed with the injector
Always replace injector sealing washers and O-rings when replacing injectors
Installation Guidelines (Reference Isuzu workshop manual for complete steps):
Safety first — relieve fuel system pressure before disconnecting any fuel lines
Disconnect battery negative terminal
Remove the fuel rail and injector wiring harness
Remove the old injector from the cylinder head
Compare the new injector with the old unit — verify part number (095000-6980) matches
Inspect the injector bore and sealing surfaces for damage
Install new sealing washer and O-rings
Install the new injector into the cylinder head
Reconnect the fuel rail and wiring harness
Reconnect battery
Prime the fuel system — cycle the ignition several times to build pressure
Start engine and check for fuel leaks
Perform injector coding / adaptation using a professional diagnostic scan tool — mandatory for proper operation
Pro Tips:
Use only high-quality diesel fuel to prevent contamination and premature injector wear
Always replace the fuel filter at recommended intervals
If replacing one injector, consider having all injectors tested and balanced
Keep the injector bores clean during installation to prevent contamination
