The CSF Heat Exchanger features a 2-Row (vs OEM single row) Core that is 42mm thick with CSF'sExclusive B-Tube Technology. Increasing the size of the core and end tanks adds to the overall volume of the system which helps absorb more heat. The more efficient core not only helps dissipate more heat from the system, but also provides better airflow into the radiator that sits behind the heat exchanger. For vehicles equipped with the ZF8 Automatic Transmission, the heat exchanger core specifications were designed concurrently with CSF's Race-Spec Dual Core Transmission Oil Cooler (CSF #8221).
