Overview
The Perrin Top Mount Intercooler (TMIC) is a direct-fit upgrade designed to optimize the cooling efficiency and airflow of your turbocharged Subaru. Compatible with the 2022-2025 WRX, 2019-2025 Ascent, 2020-2025 Legacy XT, and 2020-2025 Outback XT, this intercooler replaces the restrictive OEM plastic boost tube with a high-density aluminum core and precision-engineered end tanks. It is tailored for enthusiasts seeking reliable power gains and consistent performance under demanding driving conditions without the need for immediate tuning.
Engineered with a 75% larger core than stock, the Perrin TMIC features a 3/8” bar and plate design that maximizes heat dissipation while minimizing pressure drop. The TIG-welded aluminum construction and powder-coated finish ensure durability and corrosion resistance, while the smooth end tank design reduces air turbulence for improved boost response. This intercooler also integrates seamlessly with the Perrin Strut Brace, maintaining chassis rigidity and OEM+ fitment quality.
For Subaru owners, this intercooler upgrade translates to more stable intake air temperatures, reduced heat soak, and up to 5 wheel horsepower gains without requiring ECU recalibration. Its robust design supports over 600 WHP, making it an excellent foundation for future tuning and performance modifications. Whether daily driving or pushing your Subaru on the track, the Perrin TMIC delivers consistent power and reliability.
