I have 6 Siemens injectors for sale. I don’t know if they are low or high impedance. They were on the car when I bought it. Car ran fine with them . I upgraded to a larger fuel system. $100 shipped to lower 48.
Sorry only numbers are the ones stamped on the injector in the picture (3145). I didn’t purchase these new. They were In The car when I bought it. There might be a way of crossing the stamping number but not sure.
