SKU: M00C MMTC-WRX-15
Description
Part #: MMTC-WRX-15
The CVT Transmission in the 2015-2021 Subaru WRX is an impressive system, providing smooth and seamless gear changes with the pull of a lever. However, overheating the transmission fluid can cause early component failure, especially for those interested in racing their WRX or even towing a small trailer. Mishimoto has just the solution for any high-stress situation you can throw to your CVT-equipped WRX. Mishimoto'started by placing a large 19-row oil cooler in the front of the vehicle, where it gets the most amount of airflow. The Mishimoto oil cooler kit is designed to work with the stock transmission cooler, creating a system that is ready for any challenge. When installed, the Mishimoto engineers put the transmission cooler through a series of rigorous tests, including driving the vehicle, fully-loaded with occupants and supplier, up a steep grade to measure the efficiency of the 19-row oil cooler. Mishimoto engineers saw consistent 20 Degrees Fahrenheit (6.7 Degrees Celsius) drops in transmission fluid temperatures, with temperature decreases even during normal driving. If you drive your CVT WRX hard on the racetrack or street, the Mishimoto CVT Transmission cooler is a must!
