There are a few ways to determine if your current fuel injectors are low impedance or high impedance:
Check the specifications: The most accurate way to determine the impedance of your fuel injectors is to check the specifications provided by the manufacturer. This information is typically listed in the product description or specifications and can also be found by contacting the manufacturer directly.
Use a multimeter: Another way to determine the impedance of your fuel injectors is to use a multimeter. To do this, you will need to disconnect the injectors from the wiring harness and measure the resistance between the positive and negative terminals of the injector. Low impedance injectors typically have a resistance of around 2-4 ohms, while high impedance injectors typically have a resistance of around 12-16 ohms.
Consult a professional: If you're unsure how to measure the impedance of your fuel injectors, you can consult a professional, such as a mechanic or an auto electrician. They will be able to measure the impedance and help you determine which type of injectors you have.
It is important to note that not all fuel injectors are either low impedance or high impedance. Some injectors may have a different impedance value, so it is important to check the specifications provided by the manufacturer.
Determining the impedance of your current fuel injectors is important when choosing replacement injectors or upgrading to higher flowing fuel injectors. You can check the specifications provided by the manufacturer, use a multimeter, or consult a professional to determine the impedance of your fuel injectors.
