Radium Engineering BMW M50 M52 M54 S50 S52 Fuel Rail

For a properly planned performance build, the Radium Engineering BMW M50 M52 M54 S50 S52 Fuel Rail replaces or upgrades the factory fuel rail with a high-flow rail designed for performance injectors and AN/ORB plumbing. The larger, purpose-built fuel path is useful on modified engines where injector choice, fuel volume, and serviceable external plumbing matter more than the stock rail layout.

This version is designed around BMW M50 M52 M54 S50 S52, so the mounting, routing, or connection details should be checked against that application before installation. Injector height, upper/lower O-ring diameter, and plumbing requirements vary by engine. Match the exact application and injector configuration.
