The Skunk2 Ultra Race Fuel Rail is a high-flow billet aluminum solution engineered for K-Series applications, including both Ultra Street and Ultra Race intake manifolds. This versatile fuel rail is designed to be used as a primary rail on K-Series setups and can also function as a secondary fuel rail for both K-Series and S2000 Skunk2 Ultra Race manifolds.
With a massive 17mm (0.669") internal bore and -8 ORB ports, this rail ensures unrestricted fuel delivery capable of supporting 1200+ horsepower. Constructed from CNC-machined billet aluminum and finished with a hard anodized coating, the rail is fully compatible with all fuel types—including pump gas, E85, and methanol—and offers excellent corrosion resistance under high-performance conditions.
This model replaces several discontinued Skunk2 fuel rails and brings them under one updated, high-flow, multi-application design.
