Product Description

The Radium Engineering 20-0111-02 Fuel Rail Kit is engineered specifically for the FA20 2.0 L I4 engine found in Subaru BRZ, Scion FR-S, and Toyota 86/GR86 models from 2013 through 2021. CNC-machined from billet aluminum and finished in black anodize, it replaces the OEM rail with a higher-flow design to support performance tuning, turbo or supercharger upgrades, and E85 fuel use.

Featuring a larger 0.69" internal bore and OEM injector spacing, this rail bolts directly into factory mounting points with included bracketry and hardware - no modifications needed. Compatible with both stock and upgraded injectors and fuel regulators, it ensures consistent, stable fuel delivery under demanding conditions while delivering a clean aesthetic and long-lasting performance.
