I just want to confirm what fuel injectors I should be using? I never saw the original injectors so I dont know if they were red or brown tops. When I searched I saw it mentioned that they changed injectors to high impedence mid year in 1988. How can I tell which ones I should be using. I have a s5 motor with high 550's and low 680's secondaries. The car runs fine but I do have some flooding issues. I need to redo my fuel system this year or send out my current injectors to be cleaned and wire in some resistors.

 

Mine were high imp square injectors originally. But now I'm running on low imp square injectors with a resistor pack from any S4.

 

An AE will have high impedance injectors.

The switch happend around 87.5.

 

Thanks guys. I just wanted to be sure before I ordered resistors
