The factory cooling assembly relies on composite plastic end tanks crimped onto an aluminum core via elastomer gaskets. Over prolonged thermal cycling, these crimped seams fatigue, dry-rot, and crack under system pressure—leading to catastrophic coolant loss, loss of cabin climate control, and severe engine overheating. Additionally, the OEM core density struggles to shed heat effectively during sustained performance driving or aggressive tuning profiles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty replacement utilizes 100% all-aluminum construction featuring precision TIG-welded end tanks and an advanced brazed tube-and-fin core architecture. Eliminating the failure-prone plastic tanks and crimp joints entirely, it provides superior structural integrity and burst-pressure resistance. The optimized core design maximizes surface area contact and coolant flow velocity, mitigating thermal soak and accelerating heat dissipation. Direct-fit mounting points and factory-spec quick-disconnect hose provisions ensure seamless installation into the factory core support without custom fabrication.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2013-2018 Audi S6,S7\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e4.0T V8 EA824\u003c\/strong\u003e \/ \u003cstrong\u003eC7, C7.5\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e420–450 hp \/ 406 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e4G0121251E\u003c\/strong\u003e, \u003cstrong\u003e13683\u003c\/strong\u003e, \u003cstrong\u003eDPI13683\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2018 Audi S6 4.0L V8 Turbocharged\u003c\/li\u003e\n  \u003cli\u003e2013-2018 Audi S7 4.0L V8 Turbocharged\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the C7 \/ C7.5 S6,S7?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2013-2018 Audi S6,S7 equipped with the \u003cstrong\u003e4.0T EA824\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this radiator accommodate the factory transmission cooler lines?\u003c\/strong\u003e\u003cbr\u003e Yes, all internal passages and external connection points retain OEM alignment to ensure seamless integration with the factory cooling layout.\u003c\/p\u003e\n\n\u003ch3\u003eThe Audi Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to satisfy demanding European performance standards, this cooling upgrade maintains strict OEM tolerances while preventing CEL warnings and eliminating thermal throttling on tuned or hard-driven 4.0T platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50551511974136,"sku":"DS-E9MVDZ9Y5","price":320.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-audi-s6-s7-2013-2018-4-0l-1.jpg?v=1789779193","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-audi-s6-s7-2013-2018-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
