ok here they are on my s5 lower intake manfold. Do i need to keep any of these? and what do they do.

 

the top 2 facing each other connent together to equal the pressure across the oil injectors.. if you are removing the OMP. cap em don't know the others.

 

ok cool so that mean the top 3 are done.

 

bump.

 

ya I was right about the 2 facing each other

 

The one to the far right of your pic. To the back of the engine, goes to your FPR(secondary fuel rail).

 

shop manual

its been my experience that you want all the lines correctly routed, unless you arent using that component.

so i think you want to keep the one that goes between the injectors, and the one that goes from the lower intake to the top

thxs everyone, but general concensus is that i don't need any of em, they are all for the oil injectors, i might use one for my FPR, but the rest get capped. I think i might try and email Mazda about them, i would goto a dealer, but i know more than they do
