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.

No worth buying
Size: 24+19
Not worth buying, 1 month after installation they stopped working well you could see the rubber piece that makes contact with windshield was loose on the verge of coming off, it was put on our 22 civic one that isnt used very often, so the fact that they died out so easily was disapointing, i plan on looking for some better ones and avoiding this brand 👎

Recommend!
Size: 24+19+10
These are fantastic. They were inexpensive, which made me nervous, but they are definitely high quality. They were all 3 super easy to install. Highly recommend! They also don't leave my windows streaky.

Quality Wipers
Size: Combo Pack (23" & 19"), Style: Top Lock Narrow
These Bosch Aerotwin wipers are a perfect fit for my 2020 Audi Q5 and work exactly as expected. Installation was quick and straightforward, and they snapped right into place with no issues. They wipe smoothly and quietly, leaving the windshield crystal clear even during heavy rain. Performance feels very close to OEM quality—no streaking, no skipping, just consistent and reliable cleaning. They also hold up well at highway speeds without lifting or making noise. Overall, a great upgrade or replacement for the Q5. Highly recommend if you want dependable, factory-style performance without paying dealership prices.
