When designing this new cooler, CSF wanted to ensure the best possible performance while ensuring the cooler was as durable as possible. As you've seen, oil coolers and other heat exchangers can take quite a beating over time. CSF utilizes an extremely rugged and durable Bar/Plate design which can stand up to far more abuse. The "Aero-Flow" Bar design reduces weight compared to other Bar/Plate designs while maintaining maximum strength and air-flow. These "Aero-Flow" bars improve heat dissipation with high density turbulated multi-louvered fins. Turbulation increases the turbulent flow through a tube, effectively increasing heat exchange rates and abilities. At around 50% larger in size, the CSF Oil Cooler increases both fluid capacity and core surface area. The overall performance of the Oil Cooler far exceeds the factory cooler's limits. 100% All-Aluminum construction ensures the best performance and durability. In addition, the black powder coat finish provides extra protection and offers an OEM look behind the grille of your E30. Whether you are looking to build a track car, weekend warrior, or just upgrading your restoration project, the CSF Group A / DTM Race Style Oil Cooler is the best choice for your E30.
