Description
The Mishimoto MMOC-WRX-15 is a direct-fit oil cooler kit engineered specifically for the 2015+ Subaru WRX and its FA20DIT turbocharged engine. Built around a large 19-row bar-and-plate cooler with a silver anodized finish, this kit works alongside your WRX’s factory liquid-to-liquid oil cooler rather than replacing it, giving your turbocharged, AWD-equipped WRX extra oil cooling capacity for demanding driving.
Prolonged aggressive driving, track sessions, and engine modifications all place extra thermal stress on the FA20DIT’s oil, and the stock liquid-to-liquid cooler on its own can struggle to keep up. This Mishimoto oil cooler kit is designed to reduce oil temperatures and help protect engine internals over the long haul. It uses an application-specific, CNC-machined aluminum sandwich plate engineered to clear the stock oil filter, along with a CNC-machined aluminum spacer, preassembled stainless steel braided lines with -10AN fittings, and application-specific mounting brackets that position the cooler low in the front bumper for maximum airflow. In testing, the setup delivered a +25 degree Fahrenheit (13.9 degree Celsius) drop in oil temperature with minimal pressure loss, while also increasing oil capacity by 0.75 qt.
