🔧 Vehicle Compatibility

💪 Performance Benefits

With supporting mods and proper tuning:

  • Improved top-end power — sustains stronger acceleration at higher RPM
  • Clean atomisation — excellent fuel delivery pattern for efficient combustion
  • Proven reliability — tested in real-world Australian builds

⚠️ Installation & Tuning Requirements

Professional installation essential:

  • Injectors recommended to be bench tested & shimmed after nozzle installation to ensure correct flow balance
  • Custom ECU tuning is required to safely utilise the increased fuel delivery
  • Supporting modifications recommended: upgraded turbo, intercooler, exhaust
  • EGT monitoring strongly recommended for tuned builds

⚠️ Not a DIY install: Injector nozzle replacement requires specialised tools, knowledge, and bench-testing equipment. Professional diesel technician installation strongly recommended.

❓ Frequently Asked Questions

Q: Do I need a tune after installing these nozzles?

A: Yes. A custom ECU remap is strongly recommended to optimise fueling, rail pressure and timing while keeping EGTs under control.

Q: Are these nozzles a direct fit for 4N15 injectors?

A: Yes. They replace the factory 4N15 nozzles, however professional installation, flow-testing and shimming is required.

Q: What sort of gains can I expect?

A: With turbo, intercooler, exhaust upgrades and tuning, customers report significant torque increases and stronger top-end power. Results vary by setup and tune.

Q: Do I need to recode the injectors?

A: If new calibration data is generated after testing, updated injector codes may be supplied. If injector bodies are reused, original codes are often retained — confirm with your tuner.

Q: Will this affect warranty or road legality?

A: Performance modifications can affect manufacturer warranty and compliance. Always check local regulations and confirm with your tuner and insurer.

Q: Can I install these myself?

A: Not recommended. Injector nozzle replacement requires specialised tools, bench-testing equipment, and diesel injection expertise. Professional installation strongly recommended.

Q: What's the difference between nozzles and complete injectors?

A: Nozzles are the precision spray tips that atomise fuel. This listing is for nozzles only — you reuse your existing injector bodies. Complete injectors include body, nozzle, solenoid, and all internal components.

Q: Are these genuine MCR nozzles?

A: Yes. Japanese-manufactured to MCR performance specifications. Not aftermarket copies.
