Mishimoto 15 Subaru STI Oil Cooler Kit - Black

The Subaru WRX STI is a performance machine, and keeping its engine oil temperatures in check is key to consistent power and long-term reliability. This Mishimoto oil cooler kit is specifically developed for the 2015-2018 Subaru WRX STI, making it a smart addition whether you're hitting the track or just enjoying spirited drives.

This kit features a substantial 19-row oil cooler that mounts in the front bumper, where it can catch the most airflow for efficient cooling. Mishimoto includes direct-fit mounting brackets and pre-assembled stainless steel lines with -10AN fittings, which makes installation straightforward. You can expect a reduction of over 20 degrees Fahrenheit in oil temperatures with minimal pressure loss, and the kit also comes with thermal reflective wrap to shield the lines from heat radiating off the nearby exhaust system. You can choose between a sleek black or silver cooler, and pair it with either the standard or thermostatic sandwich plate to best suit your needs.

This kit works alongside your vehicle's stock liquid-to-liquid oil cooler, adding an extra layer of temperature control. As with all Mishimoto products, this oil cooler kit is backed by their Lifetime Warranty.
