Description
The 2022+ Subaru WRX’s FA24 turbocharged engine relies on a surprisingly small liquid-to-liquid heat exchanger to manage oil temperature, a design that heats oil nearly as much as it cools it. Mishimoto’s direct-fit oil cooler kit, part number MMOC-WRX-22TBK, was engineered specifically to address this weak point with a 19-row bar-and-plate cooler finished in a black anodized core, giving modified and track-driven WRX owners a real solution for sustained high oil temperatures.
Rather than replacing the factory liquid-to-liquid cooler, this Mishimoto oil cooler kit works alongside it to help maintain ideal oil temperature and take stress off the primary cooling system. In dyno testing the kit delivered a 20-degree reduction in oil temperature, and it also adds 0.75 quarts of oil to the system for extra cooling capacity. Whether you’ve built up the FA24 for track days or simply want added insurance for spirited street driving, this Mishimoto oil cooler kit and its 19-row core are built to protect the engine from the kind of prolonged heat soak that can lead to catastrophic failure.
