The Powerhouse Racing Rear-Mount Transmission Cooler Kit is engineered to provide optimal cooling for the A650E/A340E transmission in the 2001-2005 Lexus IS300. This kit ensures your transmission operates at ideal temperatures, even under demanding conditions. At the core of the system is a robust 21-row fluid cooler, capable of dissipating significant heat. It is paired with a high-performance 7.5-inch SPAL fan, which delivers an impressive 366 CFM of airflow to efficiently cool the transmission fluid.
