Features
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:Â 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:Â Smoother internal geometry minimizes swirl and pressure loss inside the nozzle, no flow drama here.
- Improved Power and Efficiency:Â 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.
