About this part

Product Details

Your 2008-2014 Subaru Impreza WRX STI is a capable machine, and keeping its engine running strong means managing temperatures. This Mishimoto thermostatic oil cooler kit is designed specifically for your STI to help control oil temperatures, especially during demanding street or track use. By keeping your oil within an optimal temperature range, you help ensure consistent engine performance and extend the life of your engine components.

This kit features a large 19-row oil cooler that mounts in the front bumper for excellent airflow. It includes direct-fit brackets and pre-assembled stainless steel lines with -10AN fittings, making installation straightforward. The thermostatic sandwich plate is a key feature here, as it allows the oil to warm up to operating temperature before flowing through the cooler, which is important for engine health. Once the oil reaches a certain temperature, the thermostat opens, and the cooler goes to work, proven to reduce oil temperatures by 20 to 30 degrees while only causing a minimal drop in oil pressure. For added protection against heat soak from nearby exhaust components, the kit also comes with thermal reflective wrap for the oil lines.

This Mishimoto oil cooler kit is a well-built addition to your STI. It works alongside your stock liquid-to-liquid oil cooler, providing an extra layer of temperature management. Mishimoto backs this kit with their lifetime warranty, giving you confidence in your purchase.
