Under repeated thermal cycling and elevated boost pressure from the \u003cstrong\u003eEA888 Gen 3\u003c\/strong\u003e 2.0L TSI engine, these plastic tanks become brittle. Stress concentrations around the inlet and outlet necks routinely lead to micro-fracturing, seam separation, and catastrophic coolant loss. Additionally, the thin OEM single-row core lacks the heat dissipation surface area required to prevent rapid heat soak during aggressive driving or track sessions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a robust direct replacement, this unit features a 100% brazed aluminum 2-row dual-core design enclosed by hand-crafted, precision \u003cstrong\u003eTIG-welded\u003c\/strong\u003e end tanks. Manufactured from aircraft-grade \u003cstrong\u003eT-6061 aluminum\u003c\/strong\u003e, it eliminates mechanical crimp joints and plastic failure points entirely. The crossflow tube-and-fin configuration maximizes coolant contact area and ambient airflow exchange, lowering operating temperatures and preserving fluid viscosity. Built to accept factory mounting pins and OEM cooling lines, it installs without chassis modifications while handling significantly higher pressure thresholds.\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;\"\u003e2015-2019 Audi A3,S3 (Manual Transmission)\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;\"\u003eEA888 Gen 3 2.0L TSI \/ MQB (8V)\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;\"\u003e220-292 hp \/ 258-280 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;\"\u003e2219430, 8013529, 13529, RD-853-922-I5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015-2019 Audi A3 Base, Premium, Premium Plus, Prestige 2.0L L4 Gas (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e2015-2019 Audi S3 Premium Plus, Prestige 2.0L L4 Gas (Manual Transmission)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the MQB A3,S3?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2015-2019 Audi A3,S3 equipped with the EA888 Gen 3 engine and manual transmission.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this radiator retain factory fan shrouds and condenser mounts?\u003c\/strong\u003e\u003cbr\u003e Yes, it utilizes factory-style bracket locations to ensure compatibility with OEM fan assemblies and A\/C condensers without cutting or trimming.\u003c\/p\u003e\n\n\u003ch3\u003eThe Audi Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eEuropean turbocharged engines demand uncompromising thermal management; maintaining stable coolant temperatures protects delicate cylinder head gaskets and keeps ignition timing advanced without triggering knock-induced engine protection modes or fault codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50511734309112,"sku":"DS-ERFWNCINK","price":174.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-audi-a3-s3-2015-2019-2-0l-manual-1.jpg?v=1789418844","url":"https:\/\/performancechiptuning.com\/fr\/products\/radiator-for-audi-a3-s3-2015-2019-2-0l-manual","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
