The AMS EVO X Fuel Rail provides increased fuel flow which is necessary at higher boost levels. This CNC'd aluminum rail comes anodized in Red or Black and includes our signature AMS logo. With a -6AN (7.5 mm) diameter inlet and outlet it dwarfs the stock rail by over 25% in flow area. This is true bolt on part that will install with your factory fuel lines, fuel pressure regulator and will work with all factory style fuel injectors.
