The CSF OEM+ fender oil cooler for Porsche 964 and 993 is a drop-in upgrade that preserves factory appearance while modernizing cooling performance. Its dual-pass, high-performance tube-and-fin core and in-house stainless steel M30 "Widemouth" fittings improve flow and durability compared to the original unit. CSF reports up to 50% greater fitting flow capacity, a 10% increase in airflow, 16% larger core volume and a 6% bump in heat dissipation versus the period design. The TIG-welded, all-aluminum cooler is leak-tested and designed for plug-and-play installation in the factory location.
