The Race 520 Stage 2 nozzle provides the best fueling and atomization for extreme power (200hp+) TDIs. It features 7 hole technology with smaller orifices than our standard Race 520 Stage 1 nozzle for better atomization, more complete combustion, and increased fuel delivery capacity. Injector tuning to increase break or pop pressures is necessary when using this nozzle. This nozzle is only for kermaTDI customers running our turbos and our tuning. Please don't place an order unless you have kermaTDI approved tuning.
Injector Calibration Service: Calibration is REQUIRED when ordering these nozzles. It is the only way to properly set up your new Genuine Bosio nozzles for ideal performance. Please CLICK HERE for more details.
Please call 1-877-KERMA TDI (877-537-6283) if you have any questions about eligibility.
