Just driving on a hot day can push these SUVs toward overheating, and off-roading or towing makes it considerably worse. With these vehicles now 15-20 years old, cars still running the original radiator have typically lost further cooling efficiency from bent or damaged fins and internal tube clogging.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eAfter nearly a full year of design work and testing, developed in partnership with off-road specialists intimately familiar with VAG platforms, CSF's High-Performance Radiator addresses this at the source. A 2-row, 42mm ultra-high-performance core uses CSF's exclusive B-Tube technology alongside new 5mm ultra-efficient multi-louvered fins, together increasing heat transfer area by \u003cstrong\u003e20-25% over a traditional radiator design\u003c\/strong\u003e. 100% TIG-welded all-aluminium construction replaces the factory's plastic tank design entirely for genuinely improved durability and longevity under hard driving conditions. Real-world back-to-back testing at Loveland Pass near Denver, using two similarly equipped 955 Cayennes on the same climb, showed a steady \u003cstrong\u003e18-20°F differential\u003c\/strong\u003e - both starting at 86.8°F (86°C), with the OE-radiator car finishing at 212°F (100°C) while the CSF-equipped car finished at just 194°F (90°C).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e Factory mounting location - installs with no modifications or cutting required.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This Radiator\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e20-25% more heat transfer area\u003c\/strong\u003e - CSF's exclusive B-Tube core plus new 5mm ultra-efficient fins\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e100% TIG-welded all-aluminium construction\u003c\/strong\u003e - replaces the OEM's plastic tank design entirely\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eReal-world tested on the same mountain climb\u003c\/strong\u003e - 18-20°F cooler than OEM in back-to-back testing\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePurpose-built for demanding use\u003c\/strong\u003e - off-roading, overlanding, towing, hauling, and hot climates\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTrue drop-in fit\u003c\/strong\u003e - mounts in the factory location, no modifications or cutting required\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eGenuine fix for a well-documented platform weakness\u003c\/strong\u003e - not a theoretical upgrade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eCompatibility\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Cayenne (955, 2003-2006, 3.2L V6\/4.5L V8, NA \u0026amp; Turbo)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Cayenne (957, 2008-2010, 3.6L V6\/4.8L V8, NA \u0026amp; Turbo)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Cayenne S\/Turbo\/Turbo S (955\/957)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAudi Q7 (4L, 2007-2015) - shares this radiator platform\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eVolkswagen Touareg (7L) - shares this radiator platform\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54441579577677,"sku":"CSF-7227","price":1110.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-porsche-955-957-cayenne-high-performance-radiator.webp?v=1785574520","url":"https:\/\/i6tuning.com\/products\/csf-porsche-955-957-cayenne-high-performance-radiator","provider":"Inline6 Tuning","version":"1.0","type":"link"}
