❓ 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.
