Authorized Dealer


The 2022+ WRX has tons to offer with its new FA24 turbocharged engine and top-notch AWD system, but not every component lives up to the WRX’s rally pedigree. The 2022 WRX oil cooling system consists of a very small liquid-to-liquid heat exchanger that serves to heat the engine oil as much as it cools it. If you’ve modified your vehicle or spend time tracking your WRX, prolonged high oil temps can cause catastrophic failure of your FA24. Protect your investment with the Mishimoto direct-fit oil cooler kit designed specifically for the 2022+ Subaru WRX.

This 2022+ WRX performance oil cooler kit is designed to work in tandem with the stock liquid-to-liquid to maintain ideal oil temperature and alleviate stress on the primary cooling system. This kit adds 0.75-quarts of oil to the system for more cooling capacity and showed a 20-degree reduction in oil temps in dyno testing. The included 19-row oil cooler mounts in the front bumper for optimal airflow and cooling using robust application-specific brackets. This kit includes everything needed for install, including pre-assembled black nylon-covered stainless-steel lines with -10AN fittings and your choice of thermostatic or non-thermostatic sandwich plate. As with all Mishimoto products this 2022+ Subaru WRX performance oil cooler kit includes our Mishimoto Lifetime Warranty.

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.

Mishimoto fully inspects and cleans all products prior to packaging. However, it is recommended that customers flush the oil cooler with one quart of clean oil prior to installation to remove any debris accumulated during shipping.
