The DeatschWerks 7-904 is a port injection fuel rail for the BMW S58 engine used in the M2, M3, M4 and X3M. It mounts to the factory intake manifold to add a secondary set of port injectors alongside the engine's factory direct injection, increasing total fuel delivery for higher-output builds. This listing is the bare fuel rail on its own, without the plumbing kit supplied with part 7-905 or the plumbing kit and 1000cc injectors supplied with part 7-905-1000.
