Mishimoto - misMMOC-WRX-15TBK - 2015+ Subaru WRX Thermostatic Oil Cooler Kit, Black

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 Degrees Fahrenheit / 85 Degrees Celsius 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 XX Degrees Fahrenheit (XX.X Degrees Celsius) drop in oil temperatures with minimal pressure loss. The Mishimoto Subaru WRX Thermostatic Oil Cooler Kit is available with either a Sleek Silver or Stealth Black oil cooler. As with all our products, this kit includes the Mishimoto Lifetime Warranty.
