{"product_id":"csf-vag-mqb-quadruple-pass-dsg-high-performance-auxilary-radiator","title":"CSF VAG MQB Quadruple Pass DSG High-Performance Auxilary Radiator","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eOn MQB platform vehicles, the front cooling pack actually consists of three radiators working together: a center main radiator, a left-side DSG transmission heat exchanger, and a right-side auxiliary water radiator. Coolant flows from the engine into the main radiator, then splits through a Y-piece into both smaller side units, the left cooling the DSG transmission fluid through an oil-to-water cooler, and the right serving as a secondary means of lowering engine coolant temperature. Combined with the demands of harsh or track driving, all three of these factory units can become a genuine limiting factor.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCSF's Quadruple-Pass DSG High-Performance Auxiliary Radiator is a genuinely multi-fit component: it can be installed as the left-side DSG transmission heat exchanger, or, with no modifications, as the right-side auxiliary engine water radiator, giving you flexibility depending on which side of your cooling system needs attention. The 2-row, 42mm core uses CSF's exclusive B-Tube technology, increasing tube efficiency by approximately 15% over regular oval tubes for lighter, more efficient heat transfer. A genuine quadruple-pass flow structure routes coolant across the core four times before it exits, rather than just once, maximising contact time for the coolest possible outlet temperature. Full 100% all-aluminium construction, finished in black, replaces the factory's more failure-prone materials. In real-world track testing on a Golf R fitted with the full CSF MQB cooling package, adding this unit to the right side kept coolant temperatures in an optimal range with a peak of just 212°F throughout an entire demanding track day, regardless of ambient conditions.\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 fittings. For best results on both engine and transmission temperatures, CSF recommends pairing this with their matching Triple-Pass main radiator (#7084), sold separately.\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\"\u003eGenuinely multi-fit, works as either the left DSG heat exchanger or right auxiliary water radiator\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eQuadruple-pass flow structure, coolant crosses the core four times for the lowest outlet temperature\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCSF's exclusive B-Tube technology, approximately 15% more tube efficiency than regular tubes\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTrack-proven, maintained a 212°F coolant peak throughout a full demanding track day\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e100% all-aluminium construction with a black finish, no modifications required to fit\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSold individually, order two for a complete left and right upgrade\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\"\u003eVolkswagen Golf\/GTI\/Golf R (Mk7\/Mk7.5, MQB platform)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAudi A3\/S3 (8V, MQB platform)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAudi TT\/TTS (Mk3, MQB platform)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWider VAG MQB platform range, confirm exact model fitment with your supplier\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eSold individually.\u003c\/strong\u003e For a complete cooling overhaul, CSF recommends the full package: the main Triple-Pass radiator (#7084) plus one or two of this auxiliary\/DSG unit (#8132), depending on which sides your specific car uses.\u003c\/p\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":54445069205837,"sku":"CSF-8132","price":485.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/csf-vag-mqb-quadruple-pass-dsg-high-performance-auxilary-radiator.webp?v=1785678878","url":"https:\/\/i6tuning.com\/products\/csf-vag-mqb-quadruple-pass-dsg-high-performance-auxilary-radiator","provider":"i6 Tuning","version":"1.0","type":"link"}
