fuel injector indentification?
 

what is the difference between high and low impedance fuel injectors?

how can i tell if they are high or low?

how can i tell if my car takes high or low?

this is my biggest concern seeing how i have pretty much done everything i can in finding out what the problem is with the way my car is running.
i heard for the s5 models that the 10's are non turbo and the 20's are turbo but how can you tell if they are high or low? and how can i tell if my car takes high or low?

It's in the FAQ. All S5 injectors are high impedance.

if you want to know if your injectors are either low or high impedance you can ohm them out.
Get a multimeter, and find how many ohms of resistance it has.
2-4ohms is low impedance, 12-14 ohms is high impedance

Only S5 ecus will run high impedance injectors

thanks guys!

also, will the s4 fuel pump assembly work on an s5 (plug and play)?
