Mishimoto MMOC-WRX-22TSL Thermostatic Oil Cooler Kit for 2022+ Subaru WRX

Protect your 2022+ Subaru WRX and its FA24 turbocharged engine with the Mishimoto MMOC-WRX-22TSL thermostatic oil cooler kit. Designed to work alongside the factory liquid-to-liquid oil cooler, this direct-fit system helps regulate engine oil temperature during spirited driving, vehicle modifications, and track use. By reducing excessive oil temperatures, the kit helps maintain proper lubrication and reduce stress on critical engine components.
The kit includes a 19-row oil cooler mounted in the front bumper area for strong airflow and efficient heat dissipation. Dyno testing demonstrated a 20-degree reduction in oil temperature, while the added oil capacity increases the system by 0.75 quarts to support improved thermal control. Application-specific mounting brackets provide a secure installation, and the compact design integrates with the 2022+ Subaru WRX without requiring a universal fabrication approach.
Installation is simplified with pre-assembled black nylon-covered stainless-steel lines, -10AN fittings, and all required hardware. The thermostatic sandwich plate helps the engine reach operating temperature before routing oil through the external cooler, making this kit well suited for both street-driven and performance-focused vehicles. The Mishimoto MMOC-WRX-22TSL is backed by the Mishimoto Lifetime Warranty and is engineered specifically for the 2022, 2023, and 2024 Subaru WRX.
