AEM's Evolution 8 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. 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.
