How to Tell the Difference Between High-impedance of Low-impedance Injectors?

If you want to save your valuable time and resources, the last thing you want to do is get the wrong components. And when it comes to building a solid fuel system, opt for the best injectors. And that’s why understanding the differences between low and high-impedance injectors is crucial.Here’s the thing – low and high impedance injectors don’t have generalized visual parameters or indicators. Instead, you have to proactively measure the resistance between two separate electrical terminals of an injector.
In layman’s terms, the main difference between low and high impedance boils down to the coil. A low impedance injector has a resistance of 2-3 ohms throughout the injector coil. What’s more, is that you can measure this value with a standard ohm or volt meter.
On the other hand, high impedance injectors tie together with most street applications. High impedance injectors are used as saturated injectors as a highly cost-effective solution. With high impedance injectors, you can measure around 8-16ohms.
Low impedance injectors or peak-and-hold drivers involve high-pressure fuel pressure and a large injector, allowing more current to flow across the injector with utmost consistency. The circuit driver can regulate current from 4-10 amps to open the injector. Next, the circuit driver decreases the current flow to keep the injector open.
In short, it takes additional current to open the injector faster and decrease the current to ensure there is no excessive current load. The major downside of a peak and hold or high impedance injector is its high cost. Conversely, low impedance injectors are used in purpose-built applications.
