Top Mount Intercooler

The ETS Top Mount Intercooler is a high-performance upgrade designed to improve charge air cooling and consistency on the VB WRX. Featuring a significantly larger core and improved fin density over the factory unit, it reduces intake air temperatures (IATs) and helps maintain power during repeated pulls or hot conditions. Unlike the stock TMIC, which can heat soak quickly, the ETS unit offers better thermal efficiency and airflow while retaining the factory top-mount layout—making it ideal for street-driven cars that want improved performance without the complexity of a front-mount setup. It’s especially beneficial for tuned vehicles or those running higher boost levels. Fitment is clean and OEM-like, and ETS is known for high-quality welds and construction. This is a common “Stage 2+” supporting mod for owners looking to maximize consistency and reliability under load.
