Does your Dodge Ram have over 80k and have a hard start? Maybe it doesn't start at all? Maybe it misses or makes a funny ticking sound? These injectors may be what you need.
Dodge puts 10 micron fuel filters in the Cummins motor of you truck. Your injectors need a 2 micron filter to keep all of the gunk in your fuel out of them. Many people do not even get to 50k miles before they have a problem caused by fuel contamination.
Another common problem for these injectors are cracks caused by a rail pressure box. If you are using an aftermarket power enhancement and it plugs into the rail pressure, chances are its a pressure box. There are very few rail pressure boxes that are a small enough amount of pressure to be safe, so use them at your own risk. Even some downloaders have the ability to raise pressure
Injector Type: Bosch common-rail injectors
Flow Rate: Approximately 25 liters per hour (lph) at 160 MPa (megapascal)

***Bosch recommends replacing feed tube when replacing all injectors for the best fuel economy and performance. Reusing old feed tubes will lead to leaks, contamination and premature injector failure***
