If you are looking to increase the output of your 4BT Cummins engine then look no further than this economy set from the experts at Dynomite Diesel. The Economy Series injector utilizes new nozzle injector body and are built to OEM quality with slight performance gain over stock. No cheap knockoffs.

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.

Excellent value, consistent fit, cool, comfortable and durable.
Size: Large, Color: Army Green
I have purchased 20 plus of these shirts in the past six months. The first batch in spring, figuring if any inconsistencies or quality issues arose upon delivery, no problem. Amazon's return policy has always been hassle free. After trying on the fourth shirt and noticing no outstanding flaws or differences, all were simply opened, laundered and hung on a hanger. The material is 100 percent cotton, but assuming they are removed from the dryer immediately (medium heat) - no ironing necessary. No appreciable shrinking is observed and no outliers in the batch. My sport shirt size is men's US large regular fit. Other relevant sizes - 17.5 inch neck, 46 inch shoulders, 34 inch sleeves and 36 inch waist. Overall fit of these shirts is of appropriate roominess without bagginess. Shirt tail length is spot on, work dress code requires tucked in, and they stay tucked in. Casual requires not tucked in, and unless I am reaching for the sky with both hands while on tip toes, the shirt tail/ belt line is not breached. The sleeve length could have been extended by an inch since they taper to an elastic cuff, requiring that the sleeves are pulled back to original position following an extended reach. But given the choice, the sleeves as is are preferred over a straight cut without the elastic cuff. As an upgrade to the T shirt appearance of the shirt tail when not tucked in, the side seams end with a reinforced, one inch inverted V, a feature not typical in this price range. To date, durability has not been an issue. Fraying, fabric pilling and fading have not occurred. It is quite difficult, if not impossible, to differentiate the age of two duplicate color shirts purchased in two separate batches. Again, excellent value, consistent fit, cool, comfortable and durable!
