The Mishimoto CVT transmission cooler kit is a direct-fit upgrade for 2015–2021 Subaru WRX CVT models, designed to reduce transmission fluid temperatures under stress. A large front-mounted 19-row stacked-plate oil cooler works alongside the stock cooler to deliver consistent cooling. Mishimoto testing recorded a typical 20°F (6.7°C) drop in fluid temps, making this kit suitable for spirited driving, track use or light towing without cutting or vehicle modification.
