Description
The Mishimoto MMOC-WRX-22TSL is a direct-fit performance oil cooler kit engineered specifically for the 2022+ Subaru WRX and its FA24 turbocharged engine, addressing the limitations of the factory liquid-to-liquid heat exchanger that both heats and cools engine oil. Built around a 19-row oil cooler, this kit is designed for owners who have modified their WRX or spend time on track, where prolonged high oil temperatures can put the FA24 at risk.
This Mishimoto oil cooler kit works alongside the factory liquid-to-liquid cooler rather than replacing it, helping maintain ideal oil temperature while reducing stress on the primary cooling system. By adding 0.75 quarts of oil to the system, the kit increases overall cooling capacity, and in dyno testing it delivered a 20-degree reduction in oil temperature. The 19-row cooler mounts using robust, application-specific brackets designed to position it for effective airflow and cooling. As a complete Mishimoto cooler kit, everything needed for installation is included, and every Mishimoto product is backed by the Mishimoto Lifetime Warranty.
