Product Description

The PERRIN PSP-OIL-204 Transmission Oil Cooler Kit is engineered specifically for performance-oriented Subaru CVT applications in the Impreza and Forester family (model years 2013-24). With an oil cooler core that's roughly four times the size of the factory unit, this kit helps maintain optimal CVT oil temperatures during track sessions, towing, or extended high-load driving - reducing thermal stress and increasing longevity of the transmission system.

Installation is designed to integrate with the stock CVT oil cooler loop: the kit mounts at the front of the vehicle using supplied stainless steel brackets and connects to the OEM cooler lines with supplied hose and fittings. It requires removing the factory cooler loop and performing the correct fill and bleed method for the CVT oil after installation. This kit is ideal for owners of Impreza or Forester CVT vehicles seeking a serious cooling upgrade - vehicles with manual transmissions or outside the listed years are not supported by this specific part number.
