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
  • Thermostatic option available

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.

great dog toy for small and large!
Size: Medium (Pack of 1), Style: Gator
we have a very large silver lab that tears through toys, and very fast! some toys only last a day while others last a week or so... he has yet to tear this on up at all and we have had it for about 3 weeks. we also have a very small teacup yorkie, so some toys we get he cannot even play with, this one he can squeak and carry around which is great! it very quickly became one of their favorite toys! will buy again if he ever does destroy it !!! update: after a month of the lab and small yorkie playing with this some of the fabric stared to tear on the end of the toy, they still love it and it still squeaks perfectly fine. didn't think it would last this long with the big lab, will order new one when they do finally destroy it for good

A must have for my little puppers
Size: Small (Pack of 1), Style: Monkey
Bought this for a Chihuahua. He came from a bad situation that gave him screaming dreams of terror in the middle of the night, waking up, screaming. I would find him frozen in absolute terror. Poor dude. Now, he seems full of rage, and I get it because I know half of his story. And we love him anyway. He has 2 big brothers that will help show him the way, living his best life ever! Long story short; I first started buying this Petstages toy many years ago for my blind MinPin. Seeing it still, out here for sale always puts a smile on my face. Back then, they were a better quality. Now-a-days, the material around the squeaky is on the loose side, making it easier to destroy when my big dogs get it. Still, it brings back wonderful memories, is soft for a small dog that doesn’t destroy his things, it squeaks and they are usually loud (which is a must have, if you ask me), and it is cute to boot!

Had big hole in it
Color: Perching Perfection, Size: 7.5" x 6.75" x 6"
This toy had a hole in it when I got it. Like they missed a seam. I meant to return it. But I had a lot going on and forgot to. My dog loved it when I showed it to him. I handed it to him then realized it had a big hole and I had to take it away. Poor guy. He really wanted it.
