Product Details

The CSF Group A / DTM Race Style Oil Cooler for your 1988-1991 BMW M3 features an all-aluminum construction, which is key for both performance and long-term durability. This cooler is about 50% larger than the factory unit, meaning it holds more oil and has a greater surface area to dissipate heat. CSF chose a rugged bar/plate design, which is known to handle more abuse than other types, and incorporated their "Aero-Flow" bars. These bars reduce weight while still providing solid strength and improving airflow, helping the high-density, multi-louvered fins to dissipate heat more effectively by increasing turbulent flow within the cooler.

This cooler is based on the championship-winning race designs BMW used in the Group A and DTM series, which were incredibly successful in touring car racing. CSF prides itself on making upgraded parts that fit like factory units, and this oil cooler is designed to be a direct fit for your E30 M3. The cast end tanks are 100% TIG welded for a strong, leak-free connection. The black powder coat finish not only looks good behind the grille but also adds an extra layer of protection against corrosion and road debris.

This CSF oil cooler comes complete with a fitting kit that accommodates both OEM-style connections and -10 AN male fittings, giving you flexibility during installation. Whether you're building a dedicated track car, a weekend warrior, or restoring your E30, this cooler offers a significant performance upgrade over the stock unit.
