Enhance your 2015-2021 Subaru WRX STI's engine performance and longevity with the Mishimoto Subaru WRX STI Oil Cooler Kit. Specifically designed for the 2.5-liter models, this kit ensures optimal oil temperature regulation, reducing oil temps by over 20 degrees Fahrenheit (around 16 degrees Celsius) to maintain consistent engine power during spirited driving or track days. The large 19-row cooler is strategically mounted in the front bumper, allowing maximum airflow for efficient heat dissipation. This setup helps prevent oil from overheating, especially under demanding conditions, thereby extending the life of your engine components and ensuring reliable performance.

This comprehensive kit retains the use of your stock liquid-to-liquid oil cooler, making it an ideal upgrade without replacing your entire system.
