Designing the ultimate BMW E30 Oil Cooler was not an easy task. While with custom fabrication anything is possible, CSF prides itself on making upgraded products that fit like a factory unit. Fortunately, BMW already did some of the leg work for this in the late 1980s. The new CSF #8218 is based on the race proven and championship winning formula used by BMW. After BMW decided to enter Touring Car and DTM racing, they created what most would consider to be the ultimate E30 M3. In the span of about 5 years, the Group A spec M3 became the most successful touring car of all time. This race spec BMW won two champion's titles in both the European Touring Car Championship and German Touring Car Championship (aka DTM) along with countless other victories.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.
