With intercooler core dimensions of 530mm x 205mm x 95mm and a generous 10.3 liters of intercooler volume, this intercooler offers a 23.6% larger flow area and provides an impressive 95.5% more intercooler volume compared to the stock intercooler. Developed specifically for the demands of the Subaru WRX STi, our new Competition high-performance core (Tube Fin) sets new standards. The cast aluminum end boxes have been optimized using CAD technology and CFD simulations to ensure the best possible internal airflow. The intercooler inlets and outlets remain unchanged, while backpressure is minimally reduced. With our anti-corrosion coating, which has excellent heat conduction properties, your charge air cooler is optimally protected from environmental influences. This guarantees lasting and optimal cooling, accompanied by a significant increase in performance.
Installation is done in no time by replacing the OEM intercooler. Thanks to our plug-and-play feature, installation is a breeze. You don't need any technical expertise at all. Our intercooler kit for the Subaru WRX STi has been manufactured with the utmost care and is subject to constant qualitative monitoring to guarantee you the best possible quality.
