Porsche 964 / 993 OEM+ Performance Engine Oil Cooler

Click Here for the Full Press Release

To develop a truly modern cooling solution for the 964 and 993, CSF once again partnered with Porsche engine building and restoration experts at SV Auto. Their deep expertise in engine restoration and air-cooled performance provided CSF with key insights that shaped the design of this next-gen cooler. Leveraging technology from the best selling G-Body Engine Oil Cooler (a project that took over 18 months and a $20,000+ R&D investment) this new cooler brings the best modern engineering to the 911.

Engineered to fit seamlessly into concours-winning restorations, this CSF oil cooler retains a factory-style look while delivering cutting-edge performance and technology. Whether you're restoring a classic 964/993, building a high-horsepower restomod, or prepping a car for the track, this is the ultimate OEM+ and performance cooling upgrade for your 911.

The original Langerer & Reich oil cooler for the Porsche 964 and 993 was designed back in the 1980s. While it was cutting-edge at the time, it has definitely started to show its age. Even though OEM replacements are still available through the Porsche Classic program, they are built with the same outdated technology and materials as they were 30+ years ago. Replacing a clogged or failing unit with a OEM cooler may fix the immediate issues, but it won't deliver any real improvement in performance or reliability.

The new CSF oil cooler for the 964 and 993 is a true OEM+ upgrade, engineered with modern cooling technology. Its advanced core offers multiple advantages over the original tube and fin design: Innovative Rolled Fin Design - Stronger/more durable and Less Clogging. Wider air passages for improved flow. 10% Increase in airflow. 16% Larger Core Volume. 6% Increase in Heat Dissipation. No change in oil pressure vs OEM.

The TIG-Welded 100% All Aluminum construction increases the overall strength of the oil cooler. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. It is designed to be a "drop-in fit" solution; mounting in the factory location, working seamlessly with the original fan and A/C condenser, and requiring no modifications or cutting. CSF also improved the design of fan shroud mounting locations for easier installation.

CSF drew additional inspiration from its proven 911/930 Turbo Fender Oil Cooler (#8168), incorporating similarly engineered Widemouth fittings. These precision machined, threaded M30 "Widemouth" fittings are designed with an optimized inner diameter (ID) to dramatically improve oil flow. These fittings deliver up to 50% greater flow capacity compared to OEM connections. Each stainless steel fitting is crafted in-house for superior strength, durability, and long-term reliability under pressure. To ensure a perfect, leak-free seal, CSF pre-installs the fittings with high-quality copper crush washers.
