well I did research for you because I felt bad about not knowing the answer. All 4 injectors are the same and you can install them in any order as they are all identical so I wouldn't worry about ordering any more. Primaries are on the manifold closer ot the engine and seccondaries are farther away from the block.

 

thanks for the info 87....but do you know exactly where the secondaries are and how to get to them? and also will the injectors from an s5 fit into my s4 considering the s5 are high impedence and the s4 are low impedence... is there really a difference?
thanks again 87,

The secondaries are on the rail right at the top that you can see. The primaries are directly on the block which entales removal of the intake manifold to get to them.
