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.This Part Fits:

Affordable performance air filter
I was skeptical at first. How can such a quality performance air filter be so affordable? It fits perfectly and seems to perform and look exactly like the other name brand layered cotton gauze, steel meshed lifetime air filter. I sprayed some K&N oil on this thing and it feels like the engine is breathing a little easier now and performing a little better. As with anything new, your mileage will vary.

Fit perfectly, but questionably thin.
Style: CA11053A
This was an exact fit for my 2017 Kia Forte S. My only convern is that it is half the width of the stock filters. Hopefully the different material will make the difference over time. Didn't notice a loss or gain of torque or acceleration after swapping for my old dirty filter.
