If you're driving a Porsche 955 or 957 Cayenne, you probably know how crucial it is to keep that engine cool, especially if you take it off the beaten path or tow anything. Enter the CSF High-Performance All-Aluminum Radiator. These guys have been in the cooling game for a while, and they really know their stuff when it comes to Porsches. This radiator isn’t just another upgrade; it’s a serious piece of tech. The original radiator from Porsche is decent, but let’s be real—it’s a single row aluminum core with plastic tanks, and that just doesn’t cut it anymore. After 15-20 years, many of these stock radiators are losing their cooling efficiency due to bent fins and clogged tubes. CSF took all that into account when designing this radiator, and the result is impressive. What sets this radiator apart is its 5mm fin technology, which increases the heat transfer area by about 20-25% compared to the stock setup. It’s got a 2-row, 42mm aluminum core that not only boosts fluid capacity but also helps in dissipating heat like a champ. Plus, CSF’s exclusive B-Tube technology ramps up heat transfer by around 15% compared to regular tubes. It's all about maximizing airflow through the multi-louvered fins for top-notch cooling performance. Installation? Super easy. This radiator is designed to drop right into the factory location without any modifications. You won’t need to grab your cutting tools or worry about fitting issues. Just plug it in using the OEM-style inlet and outlet connections, and you're good to go. Now, for the performance nerds out there, let’s talk testing. CSF ran some serious tests at Loveland Pass, pitting two similarly equipped Cayennes against each other—one with the CSF radiator and the other with the OE radiator. They started at the same temp of 186.8°F (86°C), but the CSF radiator finished at a cool 194°F (90°C), while the OE radiator climbed up to 212°F (100°C). That’s a solid 18-20°F difference. Real-world results like that speak volumes. With a sturdy TIG-welded aluminum construction, this radiator is built to last. It’s got a hand-brushed satin finish that looks pretty slick too. Plus, it’s individually leak and pressure tested, so you know it’s reliable. Here’s a quick rundown of the specs:
  • Core Height: 710mm
  • Core Width: 551mm
  • Core Thickness: 42mm
  • Cooling Tubes: CSF's Exclusive B-Tube Technology
  • Finish: Satin
  • Drop-In Fit Installation: Yes, no modifications needed
  • Warranty: 2-Year Limited Warranty
This radiator fits:
  • Audi Q7 2007-2015
  • Porsche 955 Cayenne 2003-2006
  • Porsche 957 Cayenne 2008-2010
  • Volkswagen Touareg 2004-2010
If you want to keep your Cayenne running cool, especially under stress, this CSF radiator is a solid choice. It’s built for performance and durability, so you can hit the road or trail with confidence.

CSF takes pride in the quality of its products and offers one of the best warranty’s in the industry. Please refer to the CSF warranty card in the shipping carton for details.

CSF warranty is applicable only to the original owner of the vehicle. Original paper work verifying the proof of purchase and pre-installation cooling system checklist signed by the professional installer is required to process warranty claims.

All warranty claims should be directed to the point of purchase. Due to CSF’s established agreements with Authorized CSF Warehouse Distributors, CSF is unable to handle and/or process warranty related calls/inquires from any individuals – all inquires/warranty related claims should be directed to the point of purchase or an authorized warehouse distributor.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.

Any repairs or alterations to the unit will automatically void the warranty.

Any form of abuse, including the use of improper coolant mixtures, damage caused by steam, corrosion etc and use on commercial vehicles voids the warranty. It is the vehicle owners’ responsibility to maintain the cooling system as specified in the owners manual.
