The Radium Engineering Top-Feed Fuel Rail Conversion Kit (Part 20-0568-02) is a premium upgrade engineered for the Subaru EJ platform. It enables conversion from the factory side-feed injectors to top-feed injectors, supporting higher fuel flow and consistent delivery for high-horsepower setups.

Key Features:

  • CNC-machined from solid 6061-T6 aluminum for exceptional strength and durability

  • Black anodized finish with laser-etched branding for a clean, professional look

  • 14 mm injector bores compatible with high-flow injectors

  • Each rail includes three 8AN ORB threaded ports for flexible plumbing options

  • Billet injector seats with 14 mm lower O-ring support

  • Thermal insulating spacers reduce heat transfer from the intake manifold

  • Fully E85 compatible for ethanol-based performance builds

Why Choose This Kit:
If you’re upgrading your EJ-engine Subaru for higher horsepower or switching to E85, this conversion kit offers the flow capacity and configuration flexibility needed for performance tuning. The top-feed layout allows for greater fuel consistency and reliability under boost or track conditions.

Fitment & Installation Notes:

  • Requires top-feed injectors (14 mm lower O-ring) — injectors sold separately

  • Professional installation recommended for optimal performance and fuel line routing
