AEM Fuel Rail (Black) - 2003-2006 Mitsubishi Lancer Evolution VIII/IX

AEM 25-131BK is a high-volume fuel rail for 2003-2006 Mitsubishi Lancer Evolution VIII/IX.

A larger fuel passage supports distribution to the injectors, but usable engine fuel capacity still depends on the pump, injectors, lines, pressure regulation, and calibration.

Technical Highlights

• 1/2-inch fuel-bore design.
• Black finish.
• Additional 1/8-inch NPT port for a suitable pressure gauge/sensor or supported auxiliary connection.
• Application-specific mounting and factory-line connection arrangement.

Installation & Compatibility

Verify injector dimensions, seal condition, regulator arrangement, and fitting compatibility. Use the correct seal type at each port and pressure-test before starting. A rail upgrade does not itself increase injector flow or change the ECU calibration.

Vehicle Fitment

Match the engine, trim, and required connections as well as the model year.
