Rather than a conventional single-pass design, coolant is routed across the radiator core \u003cstrong\u003ethree times\u003c\/strong\u003e before exiting - increasing contact time and heat transfer for the lowest achievable outlet temperatures, delivering roughly \u003cstrong\u003e20-25% more cooling capacity\u003c\/strong\u003e than a standard single-pass radiator.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eAt the core is CSF's exclusive B-Tube technology - rather than a single oval tube, two \"B\"-shaped tubes provide more surface area and greater strength while allowing for thinner, lighter, more thermally efficient material. This is paired with 6.5mm tall, ultra-efficient multi-louvered fins for maximum surface area contact. CNC-machined quick-connect inlet\/outlet fittings and mounting brackets ensure a precise fit, and the radiator is a genuine drop-in replacement, accepting all OEM attaching components including quick-connect hoses, the AC condenser, mounting brackets, and fan shroud.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e Manual transmission cars directly - automatic transmission cars require a separate oil cooler alongside this radiator.\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\u003eTriple-pass flow design\u003c\/strong\u003e - coolant crosses the core three times for maximum heat rejection\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e~20-25% more cooling capacity\u003c\/strong\u003e than a conventional single-pass radiator\u003c\/li\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 - more surface area and strength than a standard tube design\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e6.5mm multi-louvered fins\u003c\/strong\u003e - maximised surface area contact for efficient cooling\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCNC-machined fittings and brackets\u003c\/strong\u003e - precise fit and long-term durability\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 - accepts all OEM attaching components, no modification required\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\"\u003eBMW E90 M3 Saloon (2008-2013, S65, manual)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW E92 M3 Coupe (2008-2013, S65, manual)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW E93 M3 Convertible (2008-2013, S65, manual)\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\u003eAutomatic transmission cars:\u003c\/strong\u003e require a separate oil cooler in addition to this radiator\u003c\/p\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54426664698189,"sku":"CSF-7059","price":879.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-bmw-m3-e90-e92-e93-triple-pass-high-performance-radiator.webp?v=1785402101","url":"https:\/\/i6tuning.com\/products\/csf-bmw-m3-e90-e92-e93-triple-pass-high-performance-radiator","provider":"Inline6 Tuning","version":"1.0","type":"link"}
