The CSF High-Performance Engine Oil Cooler is a drop-in-fit upgrade and OEM replacement for the BMW E30, developed with BMW restoration partner CA Tuned. Its rugged bar-and-plate design increases cooling capacity and durability over the 25+ year factory cooler, with cast end tanks and a matte black finish. The included fitting kit lets you run -10AN lines instead of the hard-to-source OEM rubber and hardline hoses, and it suits M20 engine-swap setups.
