Dynomite Diesel 45% Over 75 Horsepower Injector Nozzle Set 01-04 LB7 GM DuramaxDynomite'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.

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.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil

Excellent Sound Deadening Material!
Style: 10 SqFt, Style: 10 SqFt
I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

A Must Have For Car Restorations!
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

Excellent Tool for Sound Deadening and More!
This Bearing Equipped Wheel Roller is a fantastic tool that's proven incredibly useful for more than just car audio. I originally got it for installing sound deadening mat in my vehicle, and it worked perfectly. The bearing-equipped roller applies nice, even pressure, making sure the mat adheres properly without bubbles or wrinkles. It feels solid in your hand and rolls smoothly, even in tighter spots. Beyond car audio, I've used it for applying heat abatement mat and even for smoothing out seams on vinyl projects. The PU (polyurethane) material of the roller is great because it's durable but doesn't mar the surface you're working on. It's much more effective than just using your hands or a makeshift tool. Great value, with a solid feel but not heavy. It's a simple tool, but the quality of the build and the smooth operation make a big difference. If you're doing any kind of sound deadening, heat shielding, or even wallpaper/vinyl application, this roller is a must-have. It makes the job much easier and ensures a professional finish. Highly recommend it!
