Subjected to elevated underhood thermal cycles from the turbocharged \u003cstrong\u003eEA113\u003c\/strong\u003e 2.0L TFSI engine, the OEM composite material degrades and embrittles over time. This design routinely develops micro-fissures around the top hose connection neck and experiences core-to-tank seam failure under pressure spikes, inducing catastrophic coolant loss and elevated engine temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upgraded performance unit resolves factory thermal limits using an all-aluminum construction featuring precision TIG-welded end tanks fused to a furnace-brazed tube-and-fin core. By eliminating crimped plastic junctions, operating pressure thresholds are increased while thermal fatigue failure points are completely engineered out. The dense internal fin pitch increases air contact surface area, speeding thermal dissipation and resisting heat soak during aggressive track or spirited street driving. Engineered to directly replace OEM part number \u003cstrong\u003e1K0121251DM\u003c\/strong\u003e, it matches factory inlet\/outlet diameters and mounts to the OEM radiator carrier assembly seamlessly.\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;\"\u003e2009-2013 Audi TTS\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;\"\u003eEA113 (CDMA \/ CDLA) \/ 8J\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;\"\u003e265 hp \/ 258 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;\"\u003e1K0121251DM, 1K0121251AB, 1K0121251BK, 1K0121251DD, CU2822, VW3010149\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2013 Audi TTS 2.0L Turbo Base Coupe\u003c\/li\u003e\n  \u003cli\u003e2009-2013 Audi TTS 2.0L Turbo Base Roadster \/ Convertible\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the 8J TTS?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2009-2013 Audi TTS equipped with the \u003cstrong\u003eEA113\u003c\/strong\u003e 2.0L turbocharged engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes installation require modifying factory fan shrouds or coolant hoses?\u003c\/strong\u003e\u003cbr\u003e No, this unit maintains factory-spec mounting brackets and quick-disconnect hose ports to ensure full retention of original shrouds, sensors, and plumbing without trimming.\u003c\/p\u003e\n\n\u003ch3\u003eThe Audi Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European performance standards, this cooling upgrade maintains factory sensor interfaces, preserves OE coolant flow geometry, and eliminates heat-induced thermal degradation without requiring ECU recalibration or triggering instrument cluster DTC codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50551519379704,"sku":"DS-EAV74XWQ8","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-audi-tts-2009-2013-2-0l-1.jpg?v=1789779384","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-audi-tts-2009-2013-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
