DESIGN AND PERFORMANCE

When developing the intercooler, we applied our experience to focus on key factors such as increased airflow, reduced restriction, and higher flow rates, resulting in less pressure drop across the core. After 3D scanning our R&D vehicle we created a virtual model of the 2022 WRX. Using this data, we were able to design this intercooler to fit within the constraints of the tightly packaged engine bay. The new TMIC uses a 19in x 7in x 4in cross-flow core with bar and plate construction, providing a 63% increase in total volume and 209% more flow area than the stock top mount. Even with the added volume, we were able to maintain factory fitment of the charge pipe, throttle body, and hood ducting interface.

When examining the intercooler, it is immediately apparent that the billet aluminum end tanks are the standout feature. Our team made a conscious decision to depart from tradition and experiment with an innovative design approach for this iteration of the intercooler. We felt that it was important to create a product that was not only functional, but also visually aligned with the sleek and modern aesthetic of the new generation VB WRX body style.

We used 4-axis CNC milling technology to ensure that the TMIC is precisely crafted with the utmost care. By utilizing this technology, we can produce our end tanks with a higher degree of accuracy and consistency than our traditional manufacturing methods. Along with this, we were able to streamline the installation process of the billet top mount intercooler by applying the same quick release double O-ring technology used on the OEM unit, making installation a breeze from start to finish. This ensures our end tanks will not fail or leak over time. If for some reason an issue comes up, customers can depend on GrimmSpeed's well-known customer service.
