Radium Fuel Rail Only - Mitsubishi Evo 4-9

Radium Fuel Rail — Mitsubishi Lancer Evolution 4G63T (Evo 4-9)

This Radium Engineering fuel rail is CNC-machined from solid 6061 aluminium with a bright-dip anodized and laser-etched finish. Featuring a large 0.69" internal bore, it is capable of supporting all necessary engine power requirements from street builds through to high-power forced induction applications. Compatible with all fuel types including E85 and all alcohol blends.

Unlike most aftermarket Evo 8-9 fuel rails on the market, the Radium rail eliminates the OEM 2-bolt inlet flange which uses a restrictive 0.22" (5.7mm) orifice. All three ports use 8AN ORB threads for maximum flow and plumbing flexibility.

Note: This listing is for the fuel rail only — no fittings are included. All fittings must be purchased separately. This option is ideal for custom fuel system builds. For a complete installation kit, see the Radium 20-0119-PK Fuel Rail Plumbing Kit.
