ETS Front Mount Intercooler Kit Subaru STI 2015-2021

Take your Subaru STI to the next level with the ultimate front mount intercooler and piping kit from ETS. This complete kit relocates your intercooler to the front of your STI, optimizing airflow and minimizing heat soak while delivering peak performance even under high boost.

At the heart of this kit is ETS’s record-setting intercooler core, known for its exceptional cooling power. This large 26" x 11.5" intercooler core uses an advanced internal fin pack designed to handle extreme temperatures and air pressures, making it one of the most efficient options on the market. The intercooler is pressure-tested to 50 PSI and constructed with hand-fabricated, TIG-welded end tanks for maximum durability. Made in the USA, it comes with various core thickness options (3.0", 3.5", 4.0", or 5.0") and anodized finishes, allowing you to customize your setup.

The piping kit complements the intercooler with high-quality, mandrel-bent 304 stainless steel tubing, finished in a durable wrinkle black powder coat. This setup relocates the factory Subaru intercooler from the hot engine bay to the front, where it’s exposed to fresh, cool air—perfect for maximizing airflow and performance. Each pipe is beaded for secure coupler connections, while ETS Black Silicone Couplers and stainless steel T-bolt clamps ensure a tight, leak-free seal. Plus, it comes with an AIT Bung and Plug pre-installed (sensor not included), making this kit easy to install and ready for high-powered applications.

With the ETS Front Mount Intercooler and Piping Kit, your STI will experience reduced intake temperatures, better heat dissipation, and improved reliability—whether you're pushing limits on the street or the track.
