Set of 6 flow matched 120lb injectors (SMP). These are low impedance injectors, so if using the stock ECM, it needs to be modified with drivers for low impedance injectors. These are flow matched to prevent some cylinders from being leaner than others. These sometimes come in a black color or may be bare steel, but it is the same exact injector. Depending on what car these are used on, you would require a new chip, or ECM programming to work correctly
