The CSF Second Fuel Rail Kit (CSF8404) is designed specifically for CSF 8401/8402 “No Limit” air-to-air intake manifolds on BMW B58 and S58 engines. It allows you to easily add dual port injection by utilising the secondary injector provisions built into the manifold.
Supplying the same -8 ORB connection as the primary rail, this secondary rail can be configured for either return or returnless fuel systems. The kit includes the required mounting hardware so you can install it cleanly and securely on your existing CSF manifold.
