Xcessive's secondary top feed rail kit is the best way to add more injectors to your new XM intake manifold. We've added the bosses to the bottom of all our cast manifolds to allow the instalation of four secondary injectors. This rail kit comes with the rail machined for top feed Bosch style injectors (14 mm o-ring), stand off's and studs and nuts to mount directly to our manifold. The rail is threaded on both ends with 3/8" NPT to allow the use of several fitting styles.
This rail is not designed for use on stock intakes or stock injector locations.
Intake manifold, injectors and fuel line fittings not included.
