CSF Porsche 964 / 993 OEM+ Performance Engine Oil Cooler

The Porsche 964 and 993 models represent a pivotal era in the evolution of the iconic air-cooled 911 series. These vehicles, while celebrated for their performance and engineering, operated under more demanding thermal conditions compared to their predecessors. Factors such as increased engine output, stricter emissions regulations, and constrained engine bay dimensions contributed to elevated operating temperatures. Porsche’s original air/oil cooling systems, innovative for their time, began to approach the limits of their effectiveness given the technological constraints of the late 20th century. Building upon the resounding success and positive reception of the CSF 911/930 Turbo Fender Oil Cooler (#8168), CSF has expanded its portfolio with a cutting-edge OEM+ performance upgrade tailored specifically for the final air-cooled 911 generations. Introducing the CSF Porsche 964 / 993 OEM+ Performance Engine Oil Cooler — a product that seamlessly integrates modern engineering advancements with the revered design principles of Porsche’s classic air-cooled engines. Design & Engineering Excellence CSF’s commitment to delivering a superior cooling solution led to a strategic partnership with SV Auto, renowned specialists in Porsche engine restoration and performance enhancement. Their extensive expertise in air-cooled engine dynamics and restoration informed the development process, ensuring the cooler meets the highest standards of functionality and authenticity. Leveraging proprietary technology perfected during the development of the best-selling G-Body Engine Oil Cooler — a project that encompassed over 18 months of rigorous R&D and an investment exceeding $20,000 — the CSF 964/993 cooler embodies the pinnacle of modern oil cooling technology. This product is engineered to blend flawlessly into concours-level restorations, preserving the factory aesthetic while delivering enhanced thermal performance and durability. Whether your project involves restoring a classic 964 or 993, constructing a high-output restomod, or preparing a vehicle for competitive track use, this cooler represents the ultimate OEM+ upgrade, combining authentic appearance with advanced cooling efficiency. Endorsed by Industry Leaders Pfaff Tuning, a globally recognized authority in Porsche 964 performance and restoration since 2012, integrates the CSF OEM+ Performance Oil Cooler into their bespoke restoration and tuning programs. Their dedication to OEM+ authenticity and performance has made them a trusted partner for enthusiasts seeking uncompromising quality and reliability. Pfaff Tuning exclusively utilizes genuine OEM Porsche components or premium aftermarket upgrades such as the CSF cooler to ensure optimal vehicle performance and longevity. First impressions of unboxing the cooler were of the high level of quality. Fitment was no different. All the OEM lines, shroud and hardware fit perfectly in place as if the cooler was OEM. We look forward to using these coolers on all our 964 project cars going forward. Using any oil cooler other than CSF just makes no sense. Erik MorrisonParts ManagerPfaff Tuning CSF vs OEM: A Technological Advancement The original Längerer & Reich oil cooler, designed for the Porsche 964 and 993 during the 1980s, was a benchmark in cooling technology at the time. However, after more than three decades, its design and materials have become outdated. Although Porsche Classic continues to offer OEM replacements, these units replicate the original specifications without incorporating modern improvements in cooling efficiency or durability. Consequently, while OEM replacements may resolve immediate operational issues, they do not enhance performance or reliability in a meaningful way. Key Features of the CSF Oil Cooler The CSF Porsche 964 / 993 OEM+ Performance Engine Oil Cooler incorporates a suite of advanced features that significantly improve upon the original design: Innovative Rolled Fin Design: Enhances structural strength and durability while reducing susceptibility to clogging. Wider Air Passages: Facilitates improved airflow through the cooling core. 10% Increase in Airflow: Optimizes cooling efficiency by allowing greater volume of cooling air. 16% Larger Core Volume: Expands the cooling surface area for superior heat exchange. 6% Increase in Heat Dissipation: Improves the cooler’s ability to transfer heat away from the engine oil. Maintains OEM Oil Pressure: Ensures no adverse impact on engine oil pressure, preserving system integrity. Clogged Core Comparison: OEM Cooler vs CSF Cooler
