Dynomite's 75 horsepower injector nozzles are notorious for providing a very noticeable increase in power, and typically in MPG's as well, while being extremely clean out the tailpipe. The obvious main advantage to only replacing the nozzles, versus the entire injector, is price. As long as your existing injectors are in good condition with minimal wear, upgrading your nozzles can be a very cost effective way of getting the same benefits as a complete injector, but at a fraction of the cost. Once installed, these nozzles will typically add an additional 75 horsepower at the tires, yet are capable of supporting 725 RWHP with supporting modifications. Due to the size, you can even use these in conjunction with a chip or programmer without the worry of draining the fuel rail. But if you're just looking for a good bump in power and fuel economy on a completely stock truck, they are a great complement in this scenario, as well.

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.

Must wind the time adjustment knob in for it to work!
Its a gorgeous watch and I love the clasp design and band material. It works if you: 1. wind the time adjustment knob with the knob IN/towards the watch 2. pull out the time adjustment knob and wind the side button to change the time or 3. shake it hard- it starts and stays moving easily after that if you are walking/swinging your hand around. I dont know how long each wind/twist lasts but winding it (knob in) will keep it moving even if its just sitting. Options 2 or 3 only keep it moving temporarily. The band and clasp are really smooth and comfortable. The watch itself isnt too thick and the band is extremely easy to adjust to a custom fit (screwdriver and instructions included for adjusting the clasp location). Its really comfortable for an all day wear, is subtle for everyday wear but classy when looked at up close. For under $35 this is a gorgeous, simple watch and significantly cheaper than most of the others I've looked at. Havent tested under water yet though

Make sure the clasp is suitable for the environment you will be wearing it in
Color: G9901: Black band & Black dial
I don't know if I didn't look closely at the clasp pick, or if I just didn't see one, but the clasp is a bit weakly designed for everyday wear. It's come unclasped twice in the 2 weeks I've been wearing it
