CSF's Race Central Auxiliary Radiator replaces it with the same proven B-Tube core technology used across their wider Porsche cooling range.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 2-row, 42mm core uses CSF's exclusive B-Tube design - a specially engineered \"B\"-shaped tube, carefully formed and brazed over the seam, delivering approximately \u003cstrong\u003e20% more efficiency\u003c\/strong\u003e than a regular oval tube while allowing for thinner, lighter, yet stronger aluminium construction. Paired with 6.5mm multi-louvered fins for maximum surface area contact, and CNC-machined, welded OE-style brackets for genuine durability, this is a true drop-in fit - inlet\/outlet connections are designed to match the OE connections exactly, so you can reuse OEM hoses or aftermarket alternatives without modification.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eImportant - verify fitment with your VIN:\u003c\/strong\u003e some GTS 4.0 models used OE part #991-106-137-02 (matches CSF #7060), while others used OE part #991-106-138-02 (matches CSF #7068) - these are not interchangeable, so confirm your exact OE part number before ordering.\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 Auxiliary 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\u003eCSF's exclusive B-Tube core technology\u003c\/strong\u003e - ~20% more efficiency than a regular tube design\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eEliminates the OEM's plastic end tank weak point\u003c\/strong\u003e - genuine long-term reliability upgrade\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCNC-machined, welded OE-style brackets\u003c\/strong\u003e - durable, precise fitment\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 - OE-matching inlet\/outlet connections, reuses factory or aftermarket hoses\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePart of CSF's complete 991\/981 cooling range\u003c\/strong\u003e - pairs with their left\/right side radiators for a full system upgrade\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVIN-specific fitment available\u003c\/strong\u003e - two part numbers to match your exact OE configuration\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 911 Carrera (991, 2012-2019)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche 911 Carrera S\/4\/4S\/GTS\/Targa variants (991)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Cayman (981, 2014-2016)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Cayman S\/GTS\/GT4 (981)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Boxster (981, 2013-2016)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePorsche Boxster S\/GTS\/Spyder (981)\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\"\u003ePart Numbers\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\"\u003eCSF #7060 (replaces OE #991-106-137-02)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54437720850765,"sku":"CSF-7060","price":665.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-porsche-911-carrera-991-cayman-981-boxster-981-race-central-auxiliary-radiator.webp?v=1785507151","url":"https:\/\/i6tuning.com\/products\/csf-porsche-911-carrera-991-cayman-981-boxster-981-race-central-auxiliary-radiator","provider":"Inline6 Tuning","version":"1.0","type":"link"}
