Designed for applications that demand the greatest airflow and cooling capabilities, the Mishimoto WRX STI front-mount intercooler kit will provide your Subaru with the ability to make the most horsepower and torque possible. This front-mount intercooler was designed with a large, 28" intercooler core that provides the maximum cooling capability without excessive pressure drops that will wear out any turbocharger over time. The intercooler features smooth cast end tanks that are CFD tested for maximum airflow with no sharp walls or bends from cut-and-weld end tanks that disrupt airflow. The intercooler provides the best airflow and heat exchange properties for those time-attack laps, or a 10-second blast down the quarter mile.
