Dynomite Diesel 50 Horsepower Injector Set 08-10 6.4L Ford Powerstroke

The 6.4L's have proven themselves as a serious force to be reckoned with. With tuning alone, these trucks are killing much of the competition.
Nonetheless, tuning can only get you so far before you need to get your hands dirty with some hard parts upgrades. If you've come to this realization, or simply your factory injectors are in need of replacing due to wear, this set of 50 horsepower injectors from Dynomite Diesel are what you need. Another benefit to these injectors are that they do not require any custom tuning calibrations, so even if you are running out of the box SCT, Edge, Bully Dog, et-cetera tunes, they will still be a great addition to your current setup. But, it is hard to argue, that with custom tuning the benefits are even greater.

This kit comes complete with new injector lines to ensure you are not reusing your factory, contamination filled lines, which can lead to injector failure if not replaced.

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.
