AEM's Evolution 8 & 9 intake includes an aluminium inlet pipe, heatshield, and high-flow filter. All parts needed for a complete, bolt-on install are included. Although this is a very simple intake setup, it works well with the Evo 8 & 9. The system gives added throttle response and more horsepower by freeing up the air flowing to the turbocharger. This is a must have modification for a turbocharged car and should be one of the first additions you do.
