Overview
The ETS Front Mount Intercooler Core for the 2015-2021 Subaru WRX STI is a critical upgrade for enthusiasts seeking improved charge air cooling and enhanced power potential. This intercooler core is designed as a direct replacement for the factory core, delivering superior cooling efficiency without the included piping. It is ideal for STI owners who want to upgrade their intercooler performance while customizing their intercooler piping separately.
ETS is renowned for its engineering excellence and quality craftsmanship, and this intercooler core exemplifies that reputation. Featuring a record-setting core design with an advanced internal fin pack, it maximizes heat dissipation and airflow. The end tanks are hand fabricated and TIG welded, ensuring durability and precision fitment. Pressure tested to 35 PSI, this core is built to withstand high boost levels and demanding driving conditions.
For Subaru WRX STI owners, efficient intercooling is essential to maintain consistent power delivery and reduce intake air temperatures during spirited driving or track use. The large 26" x 11.5" core size provides a significant increase in cooling capacity over stock, supporting higher boost pressures and tuning potential. This intercooler core is a proven performer, with documented results such as an 8.05-second quarter mile at 184 mph by Kozmic Motorsports using an off-the-shelf ETS unit.
