BBK High-Flow Fuel Rail Kit for Camaro LS3 features the "SSI-Series" intake manifold for the 1986-1993 5.0L Mustang. The BBK engineers found that the small steel factory fuel rails leave much to be desired. This resulted in the development of our current high flow aluminum fuel rails that are included in many of our performance intake manifolds as standard equipment. While developing these fuel rails - the BBK team also made sure that these units would work stock or on other aftermarket intake manifolds so enthusiasts could get the same great performance and value that they deliver. It is built from lightweight aluminum where each rail is CNC machined to precise tolerances. It has blue anodized for maximum performance and longevity.
