Purpose-built aluminum radiator for an S54 engine swap into the E36 or E46 chassis. The core height is reduced so two race-spec oil coolers (CSF #8240 and #8032) can mount underneath in a factory-style location, and the included brackets adjust to fit both, with a separate set of brackets for an electric-fan conversion to a single 16-inch SPAL fan. The 2-row 42mm core runs CSF's B-Tube technology and 6.5mm multi-louvered fins, built from fully TIG-welded aluminum with an all-aluminum race-style drain plug and CNC-machined fittings. Two top covers (black and satin) are included for a clean OEM+ finish.
