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°F (+13.9°C) 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.

  1. Actually good.

    Make sure you line up the hoses before closing the stuff up. Had some issues and had to route it a different way even from watching the install on their site. Overall great product.

  2. Great track mod

    By Stephen July 11, 2018

    I love this thing. Wasn’t too hard to install. Went to a road track with out it and I could only go all out for 1 maybe 2 laps, for the fact that my oil temp would hit 250 easy. But with this going all out for 20 minutes straight my oil temps didn’t go over 230, and that was when it was 100 outside. Definitely worth the time and money.

  3. Awesome!

    By Chan May 15, 2018

    I live in San Diego so the temperature runs 80's on average here. My engine temp is usually 215-220. Ever since I installed this cooler, my engine has not hit over 200. On average it's around 170-180. Just last weekend I took it to Spring Mountain track in Pahrump, NV. I was pushing the engine pretty hard and hitting triple digits in the straights. Still, the engine temp stayed under 200. The average temperature in Pahrump is 85-90 when we were out there. This product works!

  4. Great oil cooler

    By Mike November 6, 2015

    My oil used to hit 235 while I was on the gas. Cruising around it would be around 212. That's to hot, after I installed the oil cooler it now sits about 180 degrees and when I get on the car it will go up about 3 degrees and holds there. My oil has hit 200 degrees twice in the past 2 months since I've had the oil cooler installed and I drive the car hard. I would definitely recommend this product to everyone. easy install and everything fit great!
