Perrin Top Mount Intercooler Black 22-25 WRX / 19-25 Ascent / 20-25 Legacy XT / 20-25 Outback XT | 75% Larger Core | High-Flow Top Mount Intercooler
Overview
The Perrin Top Mount Intercooler (TMIC) is a direct-fit upgrade designed to enhance the cooling efficiency and power delivery of turbocharged Subaru models including 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 smooth, high-flow aluminum core and end tanks engineered to minimize air turbulence. It is ideal for Subaru enthusiasts seeking reliable, consistent horsepower gains without the need for immediate ECU tuning.
Engineered with a 75% larger core than stock, the Perrin TMIC features a 3/8” bar and plate design core measuring 21.87” wide by 7.64” deep and 3.95” thick. Precision TIG-welded aluminum construction and a durable black powder coat finish ensure both longevity and a stealthy aesthetic under the hood. The intercooler is pressure tested to 50 psi and includes stainless steel inserts for secure mounting, reflecting Perrin’s commitment to quality and performance engineering.
For Subaru owners, this intercooler upgrade means improved charge air cooling, reduced pressure drop, and the potential to safely support over 600 wheel horsepower. The enhanced airflow path eliminates the factory’s two 90-degree turns, creating a more efficient air route that translates to better throttle response and consistent power delivery during spirited driving or track use. Plus, it integrates seamlessly with the Perrin Strut Brace for added chassis rigidity and style.
