Description
The Mishimoto MMOC-WRX-22SL is a direct-fit performance oil cooler kit engineered specifically for the 2022+ Subaru WRX and its turbocharged FA24 engine. Where the factory 2022 WRX oil cooling system relies on a small liquid-to-liquid heat exchanger that both heats and cools engine oil, this Mishimoto oil cooler kit works alongside that stock unit to keep oil temperatures in check when you push your WRX hard on track or after modifying it. In dyno testing, this kit showed a 20-degree reduction in oil temperature, giving owners a measurable way to protect the FA24 from the stress of prolonged high oil temps.
Beyond the temperature drop, this Mishimoto cooler kit adds 0.75-quarts of oil to the system for greater cooling capacity, and its 19-row oil cooler is mounted in the front bumper for optimal airflow using robust, application-specific brackets. As a complete oil cooler kit, it ships with pre-assembled black nylon-covered stainless-steel lines fitted with -10AN connections, plus your choice of a thermostatic or non-thermostatic sandwich plate so you can tailor the setup to daily driving, cold climates, or full-time track use. The thermostatic sandwich plate retains NPT ports for pressure or temperature sensors and accepts 160-degree, 185-degree, and 200-degree thermostats, letting the stock liquid-to-liquid cooler continue handling fast warmup while the auxiliary Mishimoto oil cooler manages sustained heat.
Vehicle Applications
This oil cooler kit is a direct fit for the 2022+ Subaru WRX equipped with the 2.4L H4 FA24F engine (chassis code VB).
