Mishimoto Thermostatic Oil Cooler Kit Subaru Impreza WRX 08+
High oil temperatures can wreak havoc on your high-performance flat four. Protect your investment with the Mishimoto direct-fit oil cooler kit designed specifically for the 2008+ Subaru WRX. The WRX has a lot to offer with its turbocharged engine and fantastic AWD system, but these vehicles are not factory-equipped with an oil cooler.
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 CNC-machined aluminium spacer provides ample room for our oil sandwich plate, making this kit compatible with the factory exhaust manifold heat shields.
This kit includes preassembled stainless steel lines with -10AN fittings and a thermal reflective wrap that deflects radiant heat from the exhaust. With this setup, your WRX can achieve a 50+°F (34+°C) drop in oil temperatures with minimal pressure loss. The Mishimoto Subaru WRX Oil Cooler Kit is available with a Sleek Silver or Stealth Black cooler and your choice of the Mishimoto Oil Sandwich Plate or the Mishimoto Thermostatic Oil Sandwich Plate, for even greater control over your oil temperatures. As with all our products, this kit includes the Mishimoto Lifetime Warranty.
