Gain 50 horsepower at the tires with great fuel economy, and an increase in throttle response by installing a set of Dynomite's Stage 1 injector nozzles that will supply enough fuel for up to 275 RWHP. This nozzle set offers excellent mileage and smoke control.

One big advantage to the 12 valves is the durability of their injectors. Unlike the newer Common Rail Cummins that have a tendency to deliver a high return rate especially once they see mileage creep towards 100k miles, the 12 valves tend to keep on ticking. What this means, is that many times, you can merely replace the injector nozzles to get the increased performance you are after, without the expense of complete injectors. Now, this isn't to say that if you have 200k miles on your stock injectors, you should only replace the nozzles, but it could be worth having them tested to confirm whether you can or not.

In comparison to the stock injectors, your mileage will typically increase 1-2 miles per gallon after your excitement wears off.

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.

IMPORTANT NOTE:

• Recommend having nozzles installed, and injector opening pressure set to 245 BAR by a qualified professional. VE Rotary injection pump should have an upgraded fuel pin installed or little to no gain will be seen from injector upgrade.
