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.

Super light and breathable, great for golf
Size: Medium, Color: White Golf Flag
I picked up the Obla Mens Golf Polo Shirt Dry Fit Performance and it’s been a great shirt for the course. The fabric is thin and stretchy, which makes it really comfortable and easy to move in. It breathes well, so you don’t feel overheated even when you’re out there for a while. Honestly, it’s so light it almost feels like you’re not wearing a shirt. The pattern looks great too, and the fit is on point, not too tight, not too loose. Pros: Lightweight and breathable Stretchy and comfortable Nice pattern/design Fits really well Cons: None so far Overall: Great golf shirt if you want something light and comfortable. Definitely one I’d pick up again

Attractive shirt and a great value
Size: X-Large, Color: Deep Purple Sunflower
Surprised by the quality. It looks more expensive than it was. It's an excellent value and fit perfectly. It's not boxy or sloppy, but looks trim and professional. The fabric is a perfect weight for Spring and Summer, and the colors and pattern are really nice. It laundered like a dream. With no shrinkage. This is versatile enough to wear on the golf course, or dressed up with a sport jacket over it. Great buy.

💲Good Value💲
Size: Large, Color: Pink Colored Dots
Purchased three in large, nice cut and fit, attractive colors/patterns, excellent price point, moderate weight material. From a few feet away these shirts look as good as a $100 polo. Under close inspection they are still nice but not designer quality. That’s fine, as the intended purpose is for golf in the Florida heat. Unlikely to shrink or fade as the material is synthetic. Economical and attractive shirts especially if you don’t care about designer labels. Hope this review was useful/helpful. ☮️

Great shirt for a great price
Size: Large, Color: White Golf Clubs
Love this shirt and ordered and received one more already. Also, lots of patterns and colors. Lightweight, perfect fit and collar holds up nicely. Has an SPF 50 to protect you when you’re out in the sun, even though it’s a lightweight shirt. It is breathable and has the quick dry wicking feature. Price is great. Highly recommend.

Nice overall
Size: Large, Color: Red Flower
Great looking shirt even though collar is not especially stable. Seem like it will be durable. The one thing I have noticed about these moisture wicking shirts is they don’t seem to be especially breathable which leads too more moisture. Good fit, great color and cut just right for a guy who is no longer like Big John, “broad at the shoulders and narrow at the hips” with a tail just right for the untucked look.
