Like the topic says, is there some benefit on using the z6 fuel rail. I have an extra one and will be installing 450's soon, just wondering if I should do this while I have all that stuff out, and if it even fits the a6 IM.
Thanks

 

I believe the FPR are on different sides

 

Well the one I have isn't is on the same side, My 97 d16y8 did have it in the other side. The a6 looks casted and small, the z6 is billet aluminum, and looks bigger. But they are probably the same inside. I don't know.
