Product Description

The Radium Engineering 20-0577-02 Fuel Rail Kit is designed for Subaru Forester XT, Impreza WRX/STI, and Legacy GT models equipped with EJ-series 2.0L turbocharged boxer engines from 2004 through 2012. This kit converts the OEM side-feed injector system to a top-feed configuration, allowing the use of high-flow top-feed injectors for improved fuel delivery.

Manufactured from CNC-machined billet aluminum with a corrosion-resistant clear anodized finish, the fuel rails offer enhanced fuel flow and durability. The kit includes an OEM-style fuel rail pressure sensor port and pre-plumbed fuel return line fittings for simplified installation.

This fuel rail kit reduces fuel pulsation and improves throttle response, designed exclusively for AWD drivetrain vehicles. Fitment for 2013 and later models is unconfirmed at this time.
