{"product_id":"csf-porsche-911-turbo-gt3-gt3-rs-991-race-central-radiator","title":"CSF Porsche 911 Turbo\/GT3\/GT3 RS (991) Race Central Radiator","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe factory central radiator on the 991 platform has a genuinely well-documented reliability problem — it's prone to both puncture and internal rotting, typically needing replacement every 5-7 years even under normal use. CSF's Race Central Radiator replaces it entirely with a proper all-aluminium upgrade, built to handle whatever forced-induction potential these engines can deliver rather than simply matching factory-plastic-tank longevity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 2-row core uses CSF's exclusive B-Tube technology — rather than a regular oval \"O\"-shaped tube, a specially engineered \"B\"-shaped tube is carefully formed and brazed over the seam, increasing heat transfer surface area by approximately 15% over regular tubes while allowing for thinner, lighter aluminium construction without sacrificing strength. Ultra-efficient multi-louvered fins are precisely aligned and wind-tunnel tested for maximum heat rejection, and CNC-machined OEM-style mounting brackets and fittings ensure a superb, durable fit. Every unit receives a genuine one-hour hand-polished mirror finish, and it's a true drop-in fit accepting all OEM attaching components, including quick-connect hoses — with a lifetime warranty backing the upgrade.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e OEM mounting points and quick-connect hoses — no modification required, true drop-in fit.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This Radiator\u003c\/h4\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\u003eCSF's exclusive B-Tube core technology\u003c\/strong\u003e - ~15% more heat transfer surface area than regular tubes\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDirectly addresses a well-known OEM failure point\u003c\/strong\u003e - factory units are prone to puncture and rotting\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLifetime warranty included\u003c\/strong\u003e - genuine peace of mind on a component known for premature failure\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCNC-machined OEM-style brackets and fittings\u003c\/strong\u003e - precise, durable fit\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHand-polished mirror finish\u003c\/strong\u003e - premium presentation to match the performance upgrade\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 - no modifications required, accepts all OEM attaching components\u003c\/li\u003e\n\u003c\/ul\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 911 Turbo (991.1\/991.2)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche 911 GT3 (991.1\/991.2)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche 911 GT3 RS (991.1\/991.2)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche 991 GT2 RS (991.2)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche 718 Cayman GT4 (981\/982) - shares this radiator platform\u003c\/li\u003e\n\u003cli\u003ePorsche 718 Cayman GTS 4.0 (981\/982) - shares this radiator platform\u003c\/li\u003e\n\u003cli\u003ePorsche 718 Cayman GT4 RS (981\/982) - shares this radiator platform\u003c\/li\u003e\n\u003cli\u003ePorsche 718 Boxster GTS 4.0 (981\/982) - shares this radiator platform\u003c\/li\u003e\n\u003cli\u003ePorsche 718 Spyder RS (982) - shares this radiator platform\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eAlso replaces OEM part number:\u003c\/strong\u003e 991 106 138 01\u003c\/p\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54428990865741,"sku":"CSF-7068","price":809.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-porsche-911-turbo-gt3-gt3-rs-991-race-central-radiator.webp?v=1785428527","url":"https:\/\/i6tuning.com\/products\/csf-porsche-911-turbo-gt3-gt3-rs-991-race-central-radiator","provider":"Inline6 Tuning","version":"1.0","type":"link"}
