Design & Engineering:
The GrimmSpeed Billet TMIC was developed using 3D scanning and CAD modeling of the 2022 WRX engine bay, ensuring perfect fitment without sacrificing any factory interfaces. The 19” x 7” x 4” bar-and-plate core provides a 63% increase in total volume and 209% more flow area than the stock intercooler, resulting in superior cooling efficiency and reduced pressure drop across the system. This allows your turbocharged engine to maintain cooler, denser intake air, reducing the risk of pre-detonation (‘knock’) while enabling consistent performance under aggressive driving conditions.
The standout feature of this intercooler is its billet aluminum end tanks. Manufactured using 4-axis CNC milling, these tanks are precisely crafted for equal flow distribution, structural rigidity, and leak-free performance. The innovative design ensures that airflow is smooth and efficient, while the sleek billet finish complements the modern aesthetic of the WRX engine bay.
Installation & Fitment:
Our billet TMIC is designed to be a direct replacement, maintaining all OEM connections, including throttle body, charge pipe, and hood scoop interfaces. The pre-installed double O-ring system ensures a secure, leak-free connection at high boost levels, while pressure testing and cleaning prior to shipment guarantees reliability right out of the box. Installation is straightforward, requires no additional tuning, and can be performed using standard tools.
