CSF's 911/930 engine oil cooler is a modern OEM+ replacement that fits early and late Porsche 911/930 models (1965–1973 and 1974–1989). It uses upgraded stainless steel "Widemouth" fittings for higher flow, a modern tube-and-fin core, Titanium-color Cerakote for extra heat dispersion, and a CNC-machined billet base plate for flat, leak-resistant mounting and improved durability.
