The GReddy Dual Clutch R35 GT-R Transmission Cooler is the premier GR6 transmission cooler available. AAM recommends this cooler for all our high HP GT-R builds - both race and street. It features Greddy's famous Blue (inner-fin) large 13row core mounted in front fender. It also includes a FRP divided air duct, similar to the OEM unit on the other side of the car for maximum cooling. More information on the product page on our online store.
