TurboXS introduces the 2008-2014 WRX and STI Cold Air Intake. As a rule of thumb on a turbocharged vehicle, you will want to free up the flow into the turbocharger allowing it to build boost much easier through a less restrictive intake path. The use of a high-quality filter element was required to keep up with the airflow demands of a 2.5L Turbocharged engine. Air is directed through a polished lightweight mandrel bent aluminum piping reducing any flow restrictions. A precisely machined mass air flow housing to ensure the sensor calibration is not altered causing any adverse effects to the vehicle’s air to fuel ratio. The kit is designed to fit with our upcoming front mount intercooler so, do not worry that you will be buying another intake in the future. Form and Function in one piece!
