2004.5-2007 Cummins BBI Stage 0.5 Fuel Injectors (MY4.5-S0.5)

Fits

These injectors originally had a flow rate of 61.8 l/h @ a pressure of 100 bar, however, once Big Bang Injection is done with them, you will see an increase of 24% when compared to stock (nozzle flow rate of 76.2 l/h/100 bar). These injectors utilize a 124° spray angle and are detuned to lower emissions and exhaust gas temperatures. You can expect to see an increase in fuel economy as they have a shorter injection duration, with the same energizing time as the OEM injectors. So if you want injectors that are capable of up to 700rwhp and still want to tow, the MY4.5-S0.5 injectors are a perfect choice!
