CSF E30 Group A / DTM Style Race-Spec Oil Cooler

While most of the engineering that went into the first M3/3-Series was top of line at the time, there is plenty of room for improvement. The cooling systems on the E30 are fairly adequate for normal to semi spirited driving. However, the factory oil cooler can still struggle to keep up under aggressive driving or track days. The vehicle is also old enough that many of the factory systems really need to be replaced.

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 designed 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.
