500% Injector Built with Brand New Components

If you're building a Cummins that lives at wide-open throttle and you're serious about fueling your horsepower goals, the Exergy 500% Over Injector is the real deal. Designed for 2007.5–2012 6.7L Cummins trucks, this injector isn’t for mild builds or daily drivers—it’s built for competition-level performance where flow, precision, and durability matter most. At 500% over stock, this injector delivers massive fuel volume—exactly what high-horsepower builds need to stay fed under heavy load and high boost. To handle that level of performance, Exergy doesn’t just open up the nozzles and call it good. Each one is micro-machined using EDM (Electrical Discharge Machining) and finished with abrasive flow honing for incredibly smooth and accurate flow paths. Then they’re tested and balanced to within 1% across the set, ensuring every cylinder is contributing equally and efficiently.

Engineered to Perform

Because flow at this level pushes beyond what a standard injector can handle, Exergy modifies the internals to preserve the proper rate shape. That’s especially important for smooth idle and clean pilot injection, which would otherwise suffer at lower RPMs. This internal work makes custom tuning absolutely essential, not just for performance but also for drivability and longevity. Everything is built and tested in-house at Exergy using specialized equipment, and each injector ships with a detailed test sheet so you know exactly how it performs. New O-rings and copper washers are included, so you’re ready to drop them in without hunting down small parts.

Fits: 2007.5, 2008, 2009, 2010, 2011, 2012 Ram 6.7L Cummins
