CSF S54 Swap Race-Spec Oil Cooler - BMW E36 / Z3 (A/C)

The CSF S54 Swap Race-Spec Oil Cooler is designed for S54 engine swaps that retain air conditioning, with a shorter right-hand side that lets owners run the A/C lines in the OEM path. It uses a dual-pass design with 8 cooling rows in turbulated heavy-duty bar-and-plate construction with fully TIG-welded extruded end tanks, and accepts the factory S54 oil-line connections. Motorsport silver finish; pairs with CSF's S54 swap all-aluminum radiator (#7211).
