High oil temperatures can wreak havoc on your high - performance FA20 DIT. Protect your investment with the Mishimoto direct - fit 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 work in conjunction with the stock liquid - to - liquid to maintain optimal oil 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 CNC - machined aluminum sandwich plate has been designed to allow proper clearance of the stock oil filter. 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 25 degree Fahrenheit (13.9 degree Celsius) drop in oil temperatures with minimal pressure loss. The Mishimoto Subaru WRX 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.
