Skunk2 Mitsubishi Evo VII/VIII/IX (4G63) Composite High Volume Fuel Rails

The Skunk2 Mitsubishi Evo VII/VIII/IX (4G63) Composite High Volume Fuel Rails are advanced fuel delivery components designed to enhance performance. Constructed from a proprietary carbon-impregnated, aerospace thermo-polymer composite, these fuel rails are 33 percent lighter and 60 percent stronger than aluminum counterparts, while operating up to 100 degrees Fahrenheit cooler. This material choice provides superior heat insulation, reducing radiant and conductive heat transfer under the hood, which results in increased horsepower and torque. The fuel rails feature large 0.625-inch internal bores for improved fuel injector pulsation dampening, along with a smooth interior finish and radius-cut injector outlets to optimize flow characteristics. The innovative design eliminates sharp internal angles common in traditional aluminum rails, ensuring better fuel flow and durability. Compatible with the factory fuel system and all fuel types, including alcohol, these rails support up to 1,200 horsepower.

Designed specifically for the Mitsubishi Evo VII, VIII, and IX equipped with the 4G63 engine, these composite fuel rails serve as a high-performance upgrade or replacement. They are a direct bolt-on fit, compatible with the factory fuel system, and suitable for street, track, or high-performance applications. The kit includes the composite fuel rails and necessary mounting hardware, providing a reliable and efficient fuel delivery solution. Whether for daily driving or racing, these fuel rails help maximize engine output by maintaining optimal fuel flow and temperature stability under demanding conditions.
