CSF vs OEM

The original OE radiator from Porsche is a plastic tank radiator with a single row aluminum core design. While this is generally accepted as good quality and durable, it just isn’t enough for the Cayenne. The 955/957 is notorious for having cooling issues. Just driving down the road on a hot day can overheat the engine and off-roading and towing/hauling is much harder on the cooling system. On top of that, these SUVs are 15-20 years old now. Those still running the original radiator have definitely lost some cooling efficiency due to bend/damaged fins and tube clogging. Needless to say, CSF had a lot of issues to address while designing this new radiator.

The CSF radiator features the latest 5mm fin technology. The smaller fin height significantly increases the heat exchange surface area improving overall cooling efficiency and recovery. A larger 2-Row 42mm aluminum core increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the ultra-efficient multi-louvered fins maximize airflow through the core for the best possible performance.
