Originally these injectors have a flow rate of 60 l/h @ a pressure of 100bar.
Our MY03 Stage 0.5 injectors use the same nozzle flow as our stage 1 injectors use. (nozzle flow rate of 78 l/h/100bar –> 30% increase compared to stock)
For model years 2003-2004 we utilize a 143° spray angle

They are detuned to lower emissions and exhaust gas temperatures. An increase in fuel economy will be noticed as they have a shorter injection duration, with the same energizing time as the OEM injectors. This makes the Stage 0.5 a perfect towing injector.

To better understand the injection quantity increase, below are the values for the full load injection quantity @1600bar/1700µs:

OEM: ~125mm³
Stage 0.5: ~150mm³ 
Stage 1: ~165mm³
