Frequently Asked Questions
Do I need a tune after installing these nozzles?
Yes — a custom ECU remap is strongly recommended to optimise fueling, rail pressure and timing. This ensures maximum power gains while keeping EGTs safe.
Are these nozzles a direct fit for 4N15 injectors?
Yes. They are designed to replace the factory 4N15 nozzles, but professional fitting, flow-testing and shimming is required for correct operation.
What sort of gains can I expect?
When paired with turbo, intercooler and exhaust upgrades plus tuning, owners have seen significant torque increases and strong top-end power. Actual results vary with supporting mods, fuel quality and tune.
Do I need to recode the injectors?
If new calibration data is generated after testing, your workshop may provide updated injector codes. If bodies are reused with just nozzle swaps, original codes are usually retained. Always confirm with your tuner.
Will this affect warranty or road legality?
Performance modifications can impact manufacturer warranty and compliance. Check local laws and confirm with your tuner and insurer before installing.
