    AEM Mitsubishi Evo 8/9 Fuel Rail Upgrade

    Maybe you’ve seen cafes or juice bars offer thicker straws with smoothies, shakes or frozen drinks. The reason is simple — if you’re sucking on a smoothie through a skimpy straw, you won’t get much flavor for your effort.

    The same thing is going on with your engine. If you have a higher-horsepower engine for racing, you need to have a strong, consistent delivery of gas. AEM’s High Volume Fuel Rail lets your Mitsubishi Evo 8/9 drink that shake with ease.

    This rail offers a ½-inch bore that keeps engines up to 1000 horsepower well quenched. If you haven’t made the jump to larger fuel injectors yet, the rail will handle your needs perfectly. But if you have graduated to bigger injectors, the rail helps dampen back pulses that they can create.

    The kit includes factory fuel line fitting, hardware, injector O-rings and comprehensive instructions. You’ve spent a lot of time working on the performance of your ’03-’06 Evo 8/9. Keep all those horses watered with this high-performance High Volume Fuel Rail.

    Worth the money.

    Bought this for my Evo VIII, and glad I did. Out of the box the rail looked amazing and everything you need for install was included. Install was easy and didn't take me long at all. The supplied O-rings actually fit better than the ones that came with my injectors. Everything went together perfectly and the rail definitely spices up the engine bay. I'm using 1500cc injectors and this rail definitely seemed like it improved flow and let those hungry injectors get all the fuel they want. Definitely would buy again.
