Looking to upgrade your Subaru Impreza, WRX, STI, Forester XT, or Legacy from 2004 to 2006? The Radium Engineering Fuel Rails Top Feed Conversion is just what you need! These fuel rails make it easy to switch from the OEM side feed fuel injector setup to a top feed system, giving you the flexibility to use high-flow fuel injectors (sold separately) that can really amp up your engine's capabilities.
When installing these fuel rails, remember that you'll need to choose appropriate fittings based on your specific setup. It's also crucial to have enough space around the fuel rail ports for larger accessories like fuel pressure regulators, gauges, and pulse dampers. The fuel rail injector bores have a generous 14mm inner diameter, ensuring they can handle all your engine's power needs.
Crafted from solid 6061 aluminum, these fuel rails are CNC machined for precision and then finished with a sleek black anodized coating. Each rail is laser engraved, giving them a high-quality look that complements your engine bay. Plus, they're compatible with all fuel types, including popular blends like E85, making them a versatile choice for any enthusiast.
Worried about heat transfer from the intake manifold? No problem! The package includes machined press-fit spacers designed to thermally insulate and protect your fuel system. The four anodized and laser-etched billet injector seats provide a secure and sealed fit for top feed fuel injectors, specifically designed for those with 14mm lower O-rings.
Just a quick note: if you're using the 20-0568-02 conversion fuel rails, steer clear of "WRX Fitment" injectors to ensure everything fits perfectly.
Upgrade your Subaru's fuel system today and enjoy the benefits of increased performance and reliability!
