ok so i just recieved 4 new injectors for my 7, the only problem is they all look the same with no distinct markings to tell me the difference between primaries and secondaries. my question is, does it matter? they have a red top to them if that means anything or helps you out. please let me know... i want my 7 back!
thanks for any advice,
-Smurf-

 

can anyone help me out with this problem of telling which injectors are primary and which one is secondary?
Thanks,
-Smurf-

 

They are the same (primaries & secondaries), but the S5 injectors are different from the S4.
