Fuel Injector Clinic Top Feed Conversion Fuel Rails With -8 Inlet & -6 Return Fittings - Black (2004 - 2006 Subaru STI / 2005 - 2006 Legacy GT) RL-STI-8-6
Convert your 2004-2006 Subaru STI or 2005-2006 Subaru Legacy GT from the factory side-feed injector configuration to a performance-oriented top-feed setup with the Fuel Injector Clinic RL-STI-8-6 Top Feed Conversion Fuel Rails. Designed specifically around Fuel Injector Clinic IS176-series top-feed high impedance injectors, this conversion rail set provides a purpose-built solution for upgrading the original fuel system while retaining factory attachment points. This RL-STI-8-6 configuration features -8AN inlet and -6AN return fittings on both sides and comes in a sleek Black anodized finish.
Fuel Injector Clinic constructs these conversion rails from high-quality aluminum extrusion precision machined to tight tolerances. The rails are anodized inside and out to provide a durable protective finish while delivering a clean, performance-focused appearance under the hood. The set includes four aluminum mounting brackets and stainless steel mounting bolts for installation using factory attachment points. The rails are threaded to accommodate -8AN fittings at each end and are specifically designed to work with FIC IS176-series Subaru STI / Legacy GT top-feed injector sets. A conversion kit may also be available for certain other top-feed injectors.

Side-Feed to Top-Feed Conversion
The RL-STI-8-6 is engineered specifically to convert the factory side-feed injector system found on 2004-2006 Subaru STI and 2005-2006 Subaru Legacy GT applications to a top-feed configuration. Fuel Injector Clinic designed these rails around its IS176-series top-feed high impedance injector sets, creating a matched rail and injector solution for these Subaru applications.
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, rail, and required conversion components can be checked for compatibility.
Important Fitment Note
The RL-STI-8-6 does not fit WRX tumblers. This rail set is specifically designed as a side-feed-to-top-feed conversion for the listed 2004-2006 STI and 2005-2006 Legacy GT applications. It should not be confused with FIC fuel rails designed for Subaru models originally equipped with factory top-feed injectors.

FAQs
What injectors are designed for the Fuel Injector Clinic RL-STI-8-6 conversion rails?
The RL-STI-8-6 rails are designed specifically around Fuel Injector Clinic IS176-series Subaru STI / Legacy GT top-feed high impedance injector sets. A conversion kit may be available for certain other top-feed injectors, so compatibility should be confirmed before ordering if you plan to use a different injector configuration.
What fitting configuration does the FIC RL-STI-8-6 use?
The RL-STI-8-6 is the -8AN inlet and -6AN return version of Fuel Injector Clinic's STI / Legacy GT top-feed conversion rail. This distinguishes it from the RL-STI-6-6 version, which uses -6AN fittings. Make sure the fitting configuration matches the fuel system you are building before ordering.
Why Buy Fuel Injector Clinic Fuel Rails From Beefcake Racing?
Converting a Subaru STI or Legacy GT from side-feed to top-feed injectors requires the rails, injectors, fittings, and supporting fuel system components to work together correctly. Beefcake Racing can help you match the RL-STI-8-6 conversion rails with the appropriate Fuel Injector Clinic IS176-series injectors and supporting components for your build.
