CSF's Dual-Pass Transmission Cooler uses proven AC condenser technology, built around a 1-row, super-high-pressure 22mm wide, 11-channel microtube core - an upgrade from the OEM's 10-tube design - paired with a high-density, multi-louvered fin design offering \u003cstrong\u003e20% more surface area contact\u003c\/strong\u003e than stock.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe dual-pass core layout means the fluid passes through the cooler twice for genuinely more effective heat rejection, not just a larger surface area for its own sake. It's engineered as a true drop-in fit, accepting all OEM attaching components - oil-line connections, mounting brackets, and shroud\/ducting - so there's no need to modify anything else in the process. A genuine must-have for fast road, track, or race use, keeping transmission fluid temperatures consistently in check during extended hard driving.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e Both DCT (7-speed) and 6-speed manual transmissions - fits in the stock location without any clearance issues.\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 Transmission Cooler\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\u003e11-channel microtube dual-pass core\u003c\/strong\u003e - genuine upgrade over the OEM 10-tube single-pass design\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e20% more surface area contact\u003c\/strong\u003e - high-density multi-louvered fin design\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 oil-line connections, mounting brackets, and ducting\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFits both manual and DCT transmissions\u003c\/strong\u003e - one core design covers both drivetrains\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eConsistent transmission temperatures under sustained hard driving\u003c\/strong\u003e - genuine track and race-proven upgrade\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\u003cstrong\u003eAlternative to OEM part 17227521376\u003c\/strong\u003e\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 Sedan (2008-2013, S65, manual \u0026amp; DCT)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW E92 M3 Coupe (2008-2013, S65, manual \u0026amp; DCT)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW E93 M3 Convertible (2008-2013, S65, manual \u0026amp; DCT)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54426211287373,"sku":"CSF-8042","price":609.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-bmw-m3-e90-e92-e93-dual-pass-transmission-cooler.webp?v=1785397221","url":"https:\/\/i6tuning.com\/products\/csf-bmw-m3-e90-e92-e93-dual-pass-transmission-cooler","provider":"Inline6 Tuning","version":"1.0","type":"link"}
