We offer four styles of injectors for the 4th-Gen Cummins:

Bosch Injectors Stock
Twisted Series Injectors +35HP
Twisted Series Injectors +50HP
Twisted Series Injectors +90HP

One of the most common mistakes people make when buying injectors is buying injectors with remanufactured parts. If the body of the injector is worn past a certain specification, you can not rebuild the injector. When injector failure occurs, the injector jams in the open position allowing a huge excess of fuel to enter the cylinder. This can cause catastrophic failures, sometimes even blowing a hole through a piston.

Injectors are crucial to the efficiency and power of a diesel engine. When injectors wear out they can cause all kinds of problems. Injectors are an engineered mechanism and are designed to handle extreme pressures (up to 29,000 psi). At those pressures, they eventually fail. Injector failure can be diagnosed by suffering fuel economy, loss of power, excessive black, white, or gray smoke. Seeing those signs tells you that you might need a new set of injectors.
