2003-2004.5 Cummins BBI Stage 4 Fuel Injectors (MY03-S4)

Fits

These injectors are designed to get the maximum amount of fuel, in the shortest amount of time, in the combustion chamber. So be careful, because these injectors are not very easy to control! These internal alterations add the advantages of increased engine response and maximum performance at high rpm. These internal body design changes can be added to BBI's Stage 1, 2 & 3 injectors by special request, please feel free to reach out for a quote!

Originally, these injectors have a flow rate of 60 l/h @ a pressure of 100 bar, however, once Big Bang Injection is done with them, you will see an increase of 163% when compared to stock (flow rate of 144 l/h @ a pressure of 100bar). Full load injection is 1600 bar/1700µs so the higher the rpm, the greater difference you will see in performance! These internal body design changes can be added to BBI's Stage 1, 2 & 3 injectors by special request, please feel free to reach out for a quote!
