Fuel Injector Clinic Top Feed Conversion Fuel Rails With -8 Inlet & -6 Return Fittings - Blue (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 Blue 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
Fuel Injector Clinic states that 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.
