Subaru EJ Top Feed Fuel Rail Conversion Kit for 2004-2006 Subaru WRX STi by Radium Engineering

The “conversion” fuel rails convert the OEM side feed fuel injector setup to top feed allowing the use of high flow fuel injectors (not included). The fuel rail injector bores are 14mm ID. Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser engraved for a high quality surface finish. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.

Each fuel rail features three 8AN ORB threaded ports (6 total). Press-fit spacers are included to thermally insulate intake
