Radium 1994-2005 Mazda Miata, MX-5 Fuel Rail 20-0369


Mazda Miata Fuel Rail By Radium

The rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high-quality surface finish.

Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors are permitted. This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused and phenolic washers are included to thermally insulate the fuel rail from the aluminum intake manifold.

This fuel rail is compatible with most Mazda 1.8L DOHC BP engines:

1994-1997 Mazda Miata
1999-2005 Mazda MX-5 
1994-1996 Eunos Roadster


  • Black Anodized Laser Etched Fuel Rail
