Fuel Injector Clinic Top Feed Conversion Fuel Rails With -6 Fittings (2004 - 2006 Subaru STI / 2005 - 2006 Legacy GT) RL-STI-6-6
Convert your factory side-feed fuel system to a performance-oriented top-feed configuration with the Fuel Injector Clinic RL-STI-6-6 Top Feed Conversion Fuel Rails. Designed for 2004-2006 Subaru STI and 2005-2006 Subaru Legacy GT applications, this rail set replaces the side-feed injector arrangement and allows the use of Fuel Injector Clinic's compatible IS176-series top-feed high impedance injector sets. Each rail includes -6AN end fittings on both sides, giving you a purpose-built foundation for upgrading the fuel delivery system while retaining factory mounting locations.
Fuel Injector Clinic manufactures these rails from high-quality aluminum extrusion that is precision machined to tight tolerances and anodized inside and out for a durable, protective finish and clean appearance. The RL-STI-6-6 set includes four aluminum mounting brackets and stainless steel mounting bolts for installation using factory attachment points. The rails themselves are threaded to accommodate -8AN fittings at each end, while this RL-STI-6-6 configuration is supplied with -6AN fittings on both ends. Matte anodized finish options include Black, Dark Blue, Dark Red, and Silver.

Top Feed Conversion
The RL-STI-6-6 rails are specifically designed to convert the factory side-feed injector configuration found on the listed STI and Legacy GT applications to a top-feed injector setup. They are engineered around Fuel Injector Clinic's IS176-series Subaru STI / Legacy GT top-feed high impedance injector sets, creating a matched solution for owners upgrading the factory fuel system.
If you plan to use top-feed injectors other than the Fuel Injector Clinic IS176-series injectors specifically designed for these rails, a conversion kit may be available. Contact Beefcake Racing before ordering so the injector and rail combination can be checked for compatibility.
Important Fitment Note
The RL-STI-6-6 fuel rails do not fit WRX tumblers. These are STI / Legacy GT side-feed-to-top-feed conversion rails and should not be confused with FIC fuel rails designed for WRX or later STI top-feed applications.
