Transform Your Subaru with Radium Engineering Fuel Rails

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.

Perfect Fit for Your Vehicle

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.

Quality Craftsmanship

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.

Thermal Insulation and Sealing

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.

What's Included

  • Black Anodized Laser Etched Aluminum Fuel Rails (x2)
  • Green Anodized and Laser Etched 22mm Injector Seats (x4)
  • Thermal Insulating Press-In Spacers, 15mm (x4)
  • Thermal Insulating Press-In Bolt Washers (x4)
  • Stainless Steel M8x1.25 Mounting Bolts (x4)

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.
