The Radium Engineering VW/Audi EA888 Fuel Rail / Port Injection is designed so it 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 Audi EA888, 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.
