Does anyone know where or who i guess makes custom primary and secondary fuel rails for the s4 13bt? I am going to run 1600cc all around and was wondering if anyone might now of a site or someone on here that does it?

 

KGparts makes some rails, check'em out.

 

you can modify your 1600s to fit the stock rail, just take a stock injector and compare where you need to grind down

 

kgparts.com or just make new one's from raw material...it's pretty easy either way...
