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.

Finally a mount for my truck!
2015 Toyota Tacoma Prerunner. I've tried many different mounts - ones that stuck to the dash, stuck to the windshield, one that mounted in the cup holder in the console. They all were bad in their own way. This Offroam mount finally got it right. Easy installation - and when I say SOLID hold I mean it. No movement, no rattle, do creaking sound, etc, etc. I was very skeptical of the one-handed use getting the phone in and out but it's really a genius design. Seriously - I just got it, so can't really speak to longevity yet. Judging by the design and quality of parts, I'll say it will be the last mount I ever purchase for this truck. Pay the extra, and be happy.

Great Quality, Perfect Fit
2015 Tacoma. This fit perfectly and is solid. Last/Different one I had on another vehicle broke one of my vent dividers. That can't happen with this design. Worth the money. Would absolutely recommend.

Well build and functions nicely
The products build quality is excellent; in fact, its far superior to this product's competitor, "Batdiary". This mount stays locked in place when i use one hand to mount my phone or remove it. Also, the internal mechanism is much nicer than the Batdiary one and feels like it has tighter and more accurate machining tolerances which should prevent it from rattling like its competitor's did after a couple weeks use. I highly recommend this product, it is worth the high price tag!

Buy once, cry once
This Offroam phone mount is not the cheapest option, but it is easily the most functional and sturdy one available, especially for second-generation Toyota Tacomas. I went through several plastic phone mounts before this and should have bought this one from the start to save both money and frustration. Installation was very simple, and it is even easier to use day to day. I like that this mount uses adjustable arms to grip the phone rather than relying on MagSafe. It keeps my phone secure even on rough terrain and offers plenty of flexibility for positioning the phone exactly where you want it.

Top notch mount with high build quality
I love it when I take a chance and spend some extra money hoping for a quality product - and it actually pans out. I bought this for my 2nd gen Toyota Tacoma (2014). The install was fast. Instructions were clear. The mount is ROCK solid and has two points of articulation so I can position my phone well. I couldn't ask for a better product. The price I paid was a little steep for a mount, but if you demand quality then look no further.
