Product Description

The Radium Engineering 20-0533-02 Fuel Rail is engineered specifically for early Mitsubishi 4G63 engines found in Evolution I-III, Galant VR4, and DSM platforms such as the Eclipse and Talon. CNC-machined from 6061-T6 aluminum with an anodized finish, this fuel rail provides a high-flow upgrade over the restrictive OEM design, supporting boosted and high-performance fuel delivery setups without excessive restriction.

Featuring four -8AN ORB ports, the 20-0533-02 fuel rail allows flexible fuel line routing and accessory integration. It reuses the OEM mounting spacers and includes phenolic insulating washers to help reduce heat transfer from the intake manifold. While designed to work with OEM-equivalent injectors, upgraded injectors are possible with matched sizing, making this rail suitable for both street and track applications.
