CSF's Dual-Pass DCT Transmission Cooler is the world's first and only true plug-and-play upgraded DCT transmission cooler for the S55 engine across the F80 M3, F82\/F83 M4, and F87 M2 Competition, engineered to significantly outperform the restrictive factory cooler.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eBuilt using CSF's AC condenser technology with a 1-row, super-high-pressure 26mm multi-channel microtube, the dual-pass high-performance core uses 10 cooling tubes versus the OEM's single-pass, 6-tube design with a separate return pipe - genuinely more effective heat rejection, not just a bigger unit. Lab tested at approximately \u003cstrong\u003e30% more efficient\u003c\/strong\u003e than the OEM cooler, this reduces thermal stress on expensive transmission components and helps preserve shift quality under sustained load. It's a true drop-in fit, accepting all OEM attaching components including oil-line connections, mounting brackets, and shroud\/ducting.\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\u003cstrong\u003eWorld's first true plug-and-play DCT transmission cooler for the S55\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDual-pass core with 10 cooling tubes\u003c\/strong\u003e - versus the OEM's single-pass, 6-tube design\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLab tested at ~30% more efficient\u003c\/strong\u003e than the factory cooler\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHigh-density multi-louvered fin design\u003c\/strong\u003e - maximises surface area contact\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\u003ePreserves shift quality and reduces thermal stress\u003c\/strong\u003e - genuine reliability upgrade under sustained hard use\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 F87 M2 Competition\/CS (S55, DCT only)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F80 M3 (2014-2018, S55, DCT only)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F82 M4 Coupe (2014-2020, S55, DCT only)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F83 M4 Convertible (2014-2020, S55, DCT only)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54427081015629,"sku":"CSF-8081","price":669.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-bmw-s55-m2-competition-m3-f80-m4-f82-f83-dct-transmission-cooler.webp?v=1785406083","url":"https:\/\/i6tuning.com\/products\/csf-bmw-s55-m2-competition-m3-f80-m4-f82-f83-dct-transmission-cooler","provider":"Inline6 Tuning","version":"1.0","type":"link"}
