Sinister Diesel - Injectors for Cummins

Dodge Cummins - Injectors for Cummins
The diesel injectors inside a modern Cummins engine are reliable and tough. But over time and hundreds of thousands of miles, they can become worn and weak.

Cummins Diesel Injectors from Sinister Diesel

Even on the best-maintained Dodge or Ram truck, the engine bay is still an incredibly harsh environment. The two main reasons for injector failure in a Cummins engine are every day wear-and-tear and contaminants in low quality fuel which damage the precision internals. A cracked injector won’t allow the fuel rail to reach adequate pressure resulting in a loss of power, poor running, increased crank times, and excessive fuel consumption and internal scoring will compromise the seal of the injectors in the cylinder which leads to power-robbing leaks and inefficient fuel atomization.
