             Brand New Bosch OEM injectors for your Cummins.  These are not remanufactured injectors!  We have two styles of injectors; the first is a Stock OEM Bosch injector, the second is our signature Twister Series Marine style injector.  Our Twister Series Injectors were developed with mileage and longevity as the driving principles.  You'll feel the difference of how your truck performs right away.

            Dodge introduced the Cummins power plant in 1989.  Rated at 160 hp from the factory, these engines used a rotary style VE Bosch pump.  These injection pumps are capable of pressures around 15,000 psi.  Even though these vehicles are known for their reliability, parts are going to wear out at pressures that high.  Injectors are essential for your Cummins to operate correctly and efficiently.  When the injectors are at the end of their life-cycle, you will begin to notice a few symptoms with your truck: 

      • Excessive black smoke
      • White or blue smoke on start-up
      • Idle surge
      • Poor mileage
      • Under-powered
      • Hard starts (Extended Cranks)
         **You will need to upgrade the turbo for +50HP, and +90HP injectors**
