BBi TowMaster STG 0.75 6.7 Cummins Injector Release

Recommended Posts

Big Bang Injection TowMaster Series Injectors:

Leaner, Meaner, Cleaner, and GREENER




Inspired by our well received stage 0.5 TowMaster 5.9 series injectors, Big Bang Injection has introduced our new MY07 Stage 0.75 Injector for the 6.7L Cummins platform.

(MY 07.5 through 2017)

Like our stage 0.5 injectors for the 5.9L Cummins, these injectors are designed to decrease EGT's and Emissions, while increasing MPG's !




MY07 Stage 0.75 injectors:


Our MY07 Stage 0.75 injectors use the same nozzle flow that our Stage 1.5 injectors use. (nozzle flow rate of 96l/h/100bar --> 45% increase compared to stock)


Stage 0.75's 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 0.75 the perfect towing injector.


To better understand the injection quantity increase, below are the values for the full load injection quantity @1800bar/1700µs:


OEM: ~150mm³


Stage 0.75: ~187mm³


Stage 1.5: ~206mm³








Hand assembled injectors built to BBI's highest quality control standards.


All of our injectors are perfectly balanced to a "full load" spread of less than 2%. (Not + or - 2%)

All BBi injectors, both NEW & remanufactured, offer a 1 year unlimited mileage warranty.
