CSF’s Ultimate BMW E30 Group A/DTM Oil Cooler (S14/M20/Swaps)

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..

IMPROVED DESIGN

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.

*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). E30 Chassis has provisions for OEM mounting hardware. OEM Mounting Hardware part numbers listed below.
