Mishimoto's direct‑fit oil cooler kit for 2006–2007 Subaru WRX and WRX STI mounts a 19‑row oil cooler behind the bumper for efficient airflow and cooling. The kit adds 0.65 qt to oil capacity, reduces temperatures with minimal pressure loss, and includes a CNC‑machined spacer for easier installation. A thermostatic sandwich plate is available for added temperature control.
