Radium Secondary Fuel Rail - Mazda Cosmo JC (13B-RE)
Application: Mazda / Eunos Cosmo JC 1990-1995 (13B-RE)
Part Type: Secondary fuel rail
Part Number: 20-0446
The Radium 13B-RE Secondary Fuel Rail is a high-flow replacement for the factory secondary rail on the Cosmo 13B-RE rotary. It is machined from aluminium, black anodised and compatible with popular fuel types including E85, with a large internal bore to support the engine's power requirements.
The rail has 11mm injector bores like the stock rail, so OEM injectors fit, and the fuel ports are tapped for 8AN ORB. An extra centre port can accept accessories such as the OEM fuel temperature sensor, a pressure transducer or a pulse damper. Included injector seat adapters allow tall aftermarket injectors to be used.
