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 186.8F (86C) to 212F (100C), the CSF-equipped vehicle’s temperature only rose to 194F (90C), showing a steady 18-20F differential.
