Whether you're in need of replacing the injectors in your LLY Duramax or you'd merely like some additional mileage, this set from Dynomite Diesel will deliver a slight gain in power while not requiring any additional modifications. These injectors will net you 10-20 rear wheel horsepower and are fully balanced for smoother operation and improved throttle response. 

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.

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.

Been buying these for years. They are relatively cheap and easy to replace, so much better than getting ripped off at the dealer lmao. Compatibility and Installation - 5/5 Filtration Efficiency and Performance - 5/5 Durability and Value for Money - 4/5 - these are made to be replaced, so can't really do much about that!

Perfect

I bought this and was able to change this myself. It was simple. I got this for my 2016 Honda Civic, I don't think I ever replaced the filter in my car in the 5 years that I had it. It had a distinct smell in my car, and once I popped this bad boy in, within a day or two the smell was gone. It did make a sound for a while like I did not do it correctly, but I did, after about a week the sound went away, so everything's good. I will buy this again when the time comes
