High Performance All Aluminum Radiator For Porsche 955/957 Cayenne (2003-2010) Models.

The original OE radiator from Porsche for the 955/957 Cayenne, with its plastic tank and single-row aluminum core, is often insufficient. These vehicles are notorious for cooling issues, especially in hot conditions, during off-roading, or while towing. With a long and successful track record with Porsche cooling systems, CSF has engineered a new high-performance radiator to address these issues and provide a superior, ultra-efficient cooling solution.

Key Features & Technology

• Ultra-High-Performance Core: A larger 2-Row, 42mm aluminum core increases fluid capacity and improves the core's ability to dissipate heat.

• 5mm Ultra-Efficient Fins: New 5mm tall fins with a multi-louvered design significantly increase the heat exchange surface area, improving overall cooling efficiency and recovery by 20-25% over a traditional radiator.

• Exclusive B-Tube Technology: The cooling tubes with CSF's exclusive B-Tube Technology increase heat transfer by approximately 15% over regular oval welded tubes

Construction & Installation

• Durable Build: Features TIG-Welded 100% all-aluminum construction for increased strength, durability, and longevity.

• OE-Style Integration: CNC machined mounting brackets and OEM style inlet/outlet ensure a perfect fit.

• "Drop-in Fit": A true plug-and-play "Drop-in Fit" installation requires absolutely no modifications or cutting.

• Finish: Hand-brushed satin finish.

• Quality Assurance: Each radiator is individually leak and pressure tested.

Real-World Performance

In testing at Loveland Pass with two similarly equipped 955 Cayennes, the CSF radiator demonstrated impressive results. While the OE radiator saw temperatures rise from 186.8°F (86°C) to 212°F (100°C), the CSF-equipped vehicle's temperature only rose to 194°F (90°C), showing a steady 18-20°F differential.
