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 675 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 or requiring dual injection pumps. 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.

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.

Perfect industrial look bookshelf
Size: 6 tier, Color: Black Brush Silver, Size: 6 tier, Color: Black Brush Silver
Surprised how good the quality was for the price. Metal is real metal and wood seems to be real wood. Pretty much twist on and off each section to put together. No question it is a very sturdy piece of furniture. Bought it over other bookshelves because the reviews said it was solid … and indeed it did turn out to be very solid. I’m very pleased and would recommend. Now I just need some things to fill the shelves.

Looks great & saves space
Color: Rustic Brown and Black, Color: Rustic Brown and Black
I couldn't be happier with the look and the space it's saving me. It came very well packaged, even with corner guards on the wood shelfs. It was very easy to assemble and attach to the end of my pantry in the kitchen. That space was just going to waste. The ladder shelf fit perfect and looks great. I love the color and texture of the wood grain, it really goes well with the black metal rail. It will be a little wobbly until you get it screwed down to the wall but after that, it's good and sturdy. The instructions were easy enough to read but I still found a couple of parts I didn't use and wondered what they were for? The parts do come numbered but only on the packaging? Not on the part itself which would have been more helpful to some extent. So just keep it all together with it's packaging and you'll have no problems. Very happy with purchase.

Nice and sleek
Color: Rustic Brown and Black
I’m really happy with the bookshelves overall, I only wish they had taller ones available. It was very quick and easy to put together and they have held up well so far. They look great for the price and I especially like that they have a small footprint when it comes to how much room they take up.

Nice, sturdy and easy to assemble.
Color: Rustic Brown and Black, Color: Rustic Brown and Black
Worked great for our small apartment. We needed something to fit over our heater baseboard and this worked! However, we had to swap the bottoms and top side rods to fit this way, meaning instead of using the 6” rods at the bottom we put them on top and used the 12” at bottom to clear over the baseboards. Easy to assemble and matched our other larger wall shelf perfectly.
