2015-2021 Subaru STI Oil Cooler Kit by Mishimoto

The Subaru STI provides a great balance of power, handling, and reliability. As with any vehicle, controlling fluid temperatures will ensure consistent power and engine longevity. The Mishimoto Subaru STI Oil Cooler Kit was developed specifically for the 2015 STI and is a great addition to any street or track-driven vehicle. A large Mishimoto 19-row cooler mounts in the front bumper to provide optimal airflow and cooling efficiency.

The included direct-fit mounting brackets and preassembled stainless steel lines with -10AN fittings will ensure an easy and hassle-free installation. This Mishimoto cooler is proven to reduce oil temperatures by 20+°F (16+°C) while maintaining minimal pressure loss. For further heat protection, this Mishimoto Subaru Oil Cooler Kit includes thermal reflective wrap for the oil lines, providing substantial heat deflection from the nearby exhaust.

The Mishimoto Subaru STI Oil Cooler Kit can be customized to meet your needs with either a Sleek Silver or Stealth Black cooler and your choice of the Mishimoto Oil Sandwich Plate or the Thermostatic Oil Sandwich Plate. As with all our products, this kit includes the Mishimoto Lifetime Warranty.

Features

  • 20+°F (16+°C) temperature drop
  • Minimal pressure loss
  • Direct fit for the 2015+ STI
  • This oil cooler kit retains the use of your stock liquid to liquid oil cooler unit
  • Sleek Silver or Stealth Black cooler options

Please Note: It is the installer's responsibility to check all thermostat plugs, NPT plugs, line fittings, and other connections to assure they are fully tightened before operating the vehicle. Mishimoto recommends that you check all connections at regular intervals, especially during the first few miles after installation.

This oil cooler kit will only work with models with the single scroll turbo and un-equal length exhaust manifold. Models with a twin scroll turbo and equal length exhaust manifold may not be compatible with this oil cooler kit.

An Amazing Addition to My Counter!
Color: Black
At first I did not think I needed this, but after using it for almost a year, I have found out how amazing this product is. It makes the coffee I get much better and lets me pack the grind much more evenly. It is also made of entirely metal, which adds a lot of weight and makes it feel super premium. After using it almost every day for a year now, I still have not needed to replace the needles, yet it came with nine more. All of that value for such a small price makes this great for me and anyone looking to improve their coffee making.

Great little tool
I recently purchased this product after upgrading my grinder. So far it had worked well and the little magnetic holder attaches perfectly to the Breville Barista Express I have. I love that it’s magnetic and keeps the tool out of the way and in a secure spot. Additionally, they throw in a double sided 3M sticky pad for those who do not have a surface where it can magnetize to. Overall great WDT with a great storage solution.

Best WDT Tool Every Espresso Lover Needs
This tool is so easy to use. It comes with a handy holder you can stick on the side of your machine and even replacement needles for the tool itself. I’ve had the tool for over a year now have not had to replace any of the needles! The 3M adhesive on the back of the holder is amazing quality. It won’t come off your machine. The tool itself helps take out the guesswork with your espresso shot, making sure the grounds are evenly distributed before you tamp.
