Radium - Fuel Rail for Mitsubishi EVO 4-9 (4G63)

The Radium Engineering Fuel Rail for Mitsubishi EVO 4–9 (4G63) delivers optimal fuel distribution for high-output Evolution builds. Extruded and CNC machined from 6061 aluminum, this rail features a huge internal bore to eliminate lean conditions in cylinder #4 and ensure equal fuel volume during violent boost transitions.

Key Performance Features:

• Massive Internal Cavity: Ample fuel volume dampens hydraulic shockwaves from high-impedance modern injectors and prevents fuel pressure spikes.
• 8AN ORB In/Out Ports: Allows high-volume feed and return line connections, plus an auxiliary top port for fuel pulse dampers or pressure sensors.
• Factory Harness Clearance: Engineered with tight tolerances to clear factory injector harness clips and vacuum ports on the 4G63 intake manifold.
• Optional OEM Plumbing Kit: Includes pre-crimped PTFE lines that snap directly into factory fuel hardlines and FPR return circuits.
• Alcohol / E85 Certified: Mil-spec black anodizing protects against degradation from high-ethanol blended fuels.

Vehicle & Engine Compatibility:

• 1996–2001 Mitsubishi Lancer Evolution 4, 5, 6 (CP9A / CN9A) - 2.0L 4G63T
• 2001–2006 Mitsubishi Lancer Evolution 7, 8, 9 (CT9A) - 2.0L 4G63T

Notice: Inlet and outlet ports are female ORB; male AN adapter fittings and hose ends are sold separately unless selecting the OEM Plumbing Kit option.
