CSF Group A / DTM Race Style Oil Cooler - E30 3-Series S14 & M20

The CSF E30 Ultimate Group A / DTM Race Style Oil Cooler is based on the size and specs of the original Group A E30 M3. This CSF engine oil cooler can be used as an upgrade on several E30 3-series models (325e/325i/325is/M3). This design employs CSF's Aero-Flow bar & plate core design, which is stronger and more efficient than the tube & fin design used on the factory BMW cooler. The durable black powder coat finish looks great and protects the aluminum cooler from damage and corrosion.

If your E30 has been treated to any kind of horsepower upgrade (engine swap, turbo, stroker), this oil cooler will help to keep the engine oil temperature in check.

Fitment Notes:

• 1986-1993 BMW E30 M3 (S14): 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). E30 Chassis has provisions for OEM mounting hardware. OEM Mounting Hardware part number listed below.
