Radium Engineering Fuel Rails VW/Audi/Bentley 6.0L W12

For a properly planned performance build, the Radium Engineering Fuel Rails VW/Audi/Bentley 6.0L W12 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.

Fitment is specific to Audi/Bentley 6.0L W12; confirm the vehicle and surrounding hardware before ordering. Injector height, upper/lower O-ring diameter, and plumbing requirements vary by engine. Match the exact application and injector configuration.
