Radium Engineering Mazda 20B-REW Secondary Fuel Rail (6 Port)

Radium Engineering designed the Mazda 20B-REW Secondary Fuel Rail (6 Port) as a purpose-built solution that 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 Mazda 20B-REW Secondary, 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.
