Upgrade the cooling of your BMW Gen 1 B58 automatic gearbox with the Burger Motorsports Transmission Oil Cooler Kit. Designed for F-chassis cars, this front-mounted air to transmission fluid radiator helps keep ATF temperatures in check for improved durability during hard driving. Supplied by Nforcd in the UK, this aftermarket cooler replaces the stock coolant-to-ATF heat exchanger and is a popular choice for B58 owners, especially those running larger-than-factory turbos.

How it works
The kit mounts behind the driver-side kidney grille to take advantage of existing airflow, dissipating excess heat from the transmission fluid. The included 165°F 74°C thermostat maintains a minimum operating temperature and bypasses the cooler until the fluid is up to temperature, helping prevent over-cooling.
