High oil temperatures can wreak havoc on your high-performance FA20 DIT. Protect your investment with the Mishimoto direct-fit thermostatic oil cooler kit designed specifically for the 2015+ Subaru WRX. The WRX has tons to offer with its turbocharged engine and fantastic AWD system, but the stock liquid-to-liquid oil cooler cannot handle prolonged aggressive driving conditions. This kit is designed to replace the stock liquid-to-liquid with a Mishimoto Sandwich Plate with Rear-Mounted Thermostat, which includes a built-in thermostat with a 185°F / 85°C activation temperature. Properly regulated oil temperatures become even more important if you have modified your vehicle or spend time tracking your WRX. Mishimoto's direct-fit oil cooler is engineered to reduce oil temperatures and extend the life of your engine. For optimal airflow and cooling, this kit includes a large 19-row cooler that is mounted in the front bumper with robust application-specific brackets. The included application-specific silicone liquid-to-liquid heat exchanger bypass hose provides a clean look in the engine bay. This kit includes preassembled stainless steel lines with -10AN fittings to help direct the oil to and from the cooler. With this setup, your WRX can achieve a 20+°F (11.1+°C) drop in oil temperatures with minimal pressure loss.
