The CSF S54 Swap Race-Spec oil cooler is engineered for S54 swap applications and features a shorter right-hand side to allow A/C lines to remain in the OEM routing. It uses a dual-pass layout with eight cooling rows in a turbulated heavy-duty bar/plate construction, accepts S54 OEM oil-line connections and is offered as a compact, high-density cooler option for S54-swapped BMW chassis.
