ive been looking i cant find the right answer . im about to buy injectors for my s4 turbo 2 . i will be buying high impedence ones since i cant find a set of low impedence ones . now i will be using a rtek 1.8 . i found a thread that says as long as i bypass the injector resitor box i can use high impedence injectors no problems on my 87 s4 . now my question is do i need s4 injectors or can i just use any high imp s5 injectors . is there a diffrence in connections or fuel rail betweek s4 and s5 ? im asking because there are 2 sets of injectors on ebay and there both high impedence one says 87-88 and other listing is 89-92 . and the 87-88 ones cost like $20 bucks more lol . let me know guys

 

s5 injector connectors are totally different, as well as the resistor elimination.

 

thanks alot man lol . so ill get high impedence s4 ones and remove the injector resistor box

 

yep, simpler to find the S4 high impedence injectors if you can't find the low impedence ones.

kg parts does sell the S5 injector clips if you have no luck with that route.
