Whether you're in need of replacing the injectors in your 6.7L Cummins or you'd merely like some additional horsepower, this set from DDP will deliver 10-20HP gain in power while not requiring any additional modifications. This set of injectors are fully balanced for smoother operation and improved throttle response. These injectors are built from a brand new injector, meaning no core charge or return!

When it comes to injectors, Dynomite Diesel is the best in the business producing performance injectors for the majority of the top performing diesel engines in the competitive landscape. But, high performance isn't their only game, they also are well known for bringing to market injectors that are extremely reliable, deliver low EGT's (Exhaust Gas Temperatures), increased fuel economy, and of course, more power. Each set of injectors are flow matched to ensure that every cylinder is fed with an equal amount of fuel for a perfectly balanced engine.

These particular injectors start life as brand new injectors from Bosch, which means that not only are you getting nothing but the best, but also are not required to return your core (old) injectors back for any type of refund.

Dynomite Diesel K-Factor Injector Nozzles – Precision. Performance. Power.
When it comes to injector nozzles, it’s not just about how much fuel you can dump, it’s about how efficiently you can deliver it. That’s where Dynomite Diesel’s K-Factor technology sets itself apart from the pack. Most aftermarket nozzles rely on standard EDM machining, quick, cheap, and dirty. But Dynomite Diesel isn’t “most.” Instead of stopping at EDM, they take it further with Advanced Flow Machining (AFM) and precision honing that smooths out imperfections, polishes internal surfaces, and radii the inlet of each orifice. The result? Clean, consistent spray patterns that make more usable power, not just smoke and heat.

Why K-Factor Nozzles Matter:

• Removes Flow Restriction at Orifice Entrance: Eliminates the natural low-pressure zone where fuel enters the orifice, allowing smoother and faster flow.
• Better Fuel Atomization: Fine mist = cleaner burn. That means less black smoke, lower EGTs, and more bang per drop of fuel.
• Delivers More Fuel at Same Pressure: Pushes more volume through a smaller hole, yes, really. It’s about optimized shape, not just size.
• Reduces Turbulence: Smoother internal geometry minimizes swirl and pressure loss inside the nozzle, no flow drama here.
• Improved Power and Efficiency: With better atomization comes better combustion, and that means more horsepower, cooler temps, and increased fuel mileage.
• Less Smoke, More Go: Bigger isn’t always better, smoky, hot tunes waste fuel. K-Factor nozzles strike the perfect balance for performance builds and daily drivers alike.

Dynomite starts with blank nozzles or custom machined pieces based on specific spray angle requirements. Each nozzle goes through a proprietary honing process, no shortcuts. The end result? A nozzle that not only flows more but does so smarter, delivering cleaner, cooler, more efficient power than the competition. Whether you're building a mild street truck or an all-out track monster, K-Factor Nozzles give you the edge where it counts, in real world performance.
