,OEM replacement fuel injector nozzle
The Diesel Fuel Injector Nozzle DLLA145PN238 / 105017-2380 / 9 432 610 461 is a direct-fit OEM replacement for ISUZU 4JB1T, 4JB1TC, and 4JG1 diesel engines, commonly found in NKR, NPR, NHR, NQR light trucks and Trooper / Bighorn SUVs. Installed in the injector body, this P-type nozzle atomizes diesel fuel into a fine mist for combustion, directly affecting engine power, fuel economy, and emissions.
Pressurized fuel from the injection pump enters the nozzle body and lifts the needle valve against spring pressure. Fuel exits through precision-drilled holes at a 145° spray cone angle, creating a fine mist that mixes with intake air for efficient combustion. Worn or clogged nozzles cause poor atomization, leading to rough idle, power loss, and increased smoke.

- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" vs. "long" pushrod variants exist within the MC828264 family.
- Always provide the VIN / chassis number for verification. Do not rely solely on cross-reference numbers.
- Clean the injector body and nozzle retaining nut thoroughly before disassembly.
- Remove the old nozzle; inspect the needle and seat for wear.
- Install the new nozzle with a new copper washer (if applicable).
- Torque the nozzle retaining nut to TBC — refer to Zexel / Denso service specifications for 105017-2380.
- Test on a diesel injector bench for opening pressure, spray pattern, and leakage before installation.
- Install the injector into the engine; torque to OEM specification. Bleed the fuel system.
Use clean, water-free diesel fuel. Replace fuel filters at OEM intervals. Inspect injectors if rough idle, smoke, or power loss develops.
