The Power Driven 24v Injector Nozzle Sets for 1998.5-2002 24v Cummins are offered as an economical option for those wanting to assemble their own diesel fuel injectors. From daily drivers to work trucks to dedicated competition vehicles, our injector nozzles have proven themselves. Each set of nozzles comes with new sealing washers, drain manifold washers, and dust seals.
What's the difference between 6-hole and 7-hole injector nozzles?
For a given flow amount, a nozzle with a smaller number of holes and a larger hole size will develop a more powerful jet of fuel, which will penetrate deeper into the piston bowl. This means the fuel jet will have some resistance to ignition until it is farther into the bowl. Conversely, a nozzle of the same flow amount, but with a larger number of holes and smaller hole size will produce a finer spray of fuel, which doesn’t penetrate as far into the bowl but ignites more readily. The amount of bowl penetration that is ideal depends on the rpm and boost level of the application.
At low rpm, the 7-hole nozzle atomizes the fuel into the charge air better, which results in increased burn efficiency. However, there is a crossover point around 2,000 rpm where the deeper penetration of the 6-hole injector nozzle is required to maintain burn efficiency at higher levels of boost and rpm, as the charge air conditions in the bowl become increasingly dense and turbulent. While apparent, these differences between 6- and 7-holes are minimal until 3,000 rpm. Overall, the 7-hole nozzle is by far the most common and is the best choice for most 24v applications. 6-hole injectors may perform better on trucks running a lot of boost and at a higher rpm.

What is the spray angle, and which one is right for me?
The spray angle, or spray pattern, is another variable in the injector equation. This refers to the built-in cone angle of the injector nozzle itself. Normally, the injector spray angle and piston bowls should be matched for optimal performance. Generally, second-gen 24v trucks with stock pistons will run best with a 153-degree spray angle, but injectors between 150 degrees and 155 degrees are used very successfully in 24v trucks.
Today, we offer a wide assortment of performance nozzles with spray angles tailored to your application.
