The CSF 997/987 Condenser utilizes a modern parallel-flow core design similar to the original OE unit. However, the CSF 16mm 10-channel microtube core offers better flow and more surface area contact for superior heat transfer. The 8mm tall multi-louvered fins further improve heat transfer over the basic fin design of the OE unit. Together, these features offer better heat dissipation for the refrigerant while increasing airflow to the radiators behind them.
