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. To give you some history on this topic, we have to go back to 1987. 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 the European Touring Car Championship and German Touring Car Championship (aka DTM) and countless other victories. The BMW Engineers had to design an oil cooler that could keep up with the added power of the race-spec engine and perform under the grueling conditions on the track. The size of the standard factory oil cooler was increased by about 50% while using the same mounts and connectors as the standard production M3. The CSF E30 Group A / DTM Race Style Oil Cooler is the same size as these race coolers with some modern upgrades/updates. While your original system may still be functional, it is likely not in the best shape. Dented, clogged, and weathered coolers just can’t perform like a new cooler. Even then, the old tube and fin design don’t compare to the durability and performance of a bar and plate design. CSF understands that most owners don’t want to change the look of their Bavarian classics at this point. That’s why the E30 Group A / DTM Oil Cooler was design to fit in the factory location with no custom mounting hardware necessary. The CSF Oil Cooler offers superior cooling capacity, modern technology, and costs less than a genuine OE replacement. 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 that can stand up to far more abuse. The CSF “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 #8218 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. Features & Specifications: Group A / DTM E30 M3 Oil Cooler Design Direct fit oil cooler for BMW E30 M3 Can fit all E30 Chassis (see applications and fitment notes) High Efficiency & Rugged Durability Bar/Plate Design “Aero-Flow” Bar Lightweight Construction for Strength and Maximum Flow Cast End Tanks with 100% Tig Welded Construction Satin Black Finish for Extreme Protection Against Corrosion and Debris Comes complete with fitting kit for both OEM style as well as -10 AN male connections Fitment Notes: 1986-1993 BMW E30 M3 (S14) The long factory oil hard line will not be able to use support brackets on the back of the radiator. This is due to the adapter fittings pushing the lines out about a ½” from factory so the brackets won’t line up but the lines will still run to the proper location and can be connected. 1985-1987 (up to 09/87) BMW E30 325 w/ Factory Oil Cooler Requires custom lines (factory hard line passes over the oil cooler normally but this unit is too tall to run that line over the top). 1988-1993 BMW E30 325 w/ Factory Oil Cooler Requires custom lines & mounting hardware. E30 Chassis has provisions for OEM mounting hardware. OEM Mounting Hardware part number listed below. 1984-1993 BMW E30 3-Series w/o Factory Oil Cooler Requires lines, mounting hardware, and sandwich plate (or provision for oil hook up).
