{"product_id":"ea839-all-aluminum-radiator-upgrade","title":"EA839 All-Aluminum Radiator Upgrade","description":"The 034Motorsport Radiator Upgrade is a high-capacity, all-aluminum radiator engineered for EA839 2.9TT or 3.0T equipped Audi vehicles, designed to address the limitations of the factory cooling system under high-performance driving conditions.\n\nManufactured in collaboration with CSF Radiators, this upgrade replaces the stock unit with a larger, all-aluminum radiator. It features a thicker performance core (42mm vs. OEM 35mm) and re-engineered billet aluminum end tanks with machined inlets and outlets for enhanced coolant flow efficiency. The radiator boasts a 40% increase in coolant capacity, from 2.5L to 3.5L, and a 16% increase in overall cooling capacity. Its design includes 65 individual 2-row B-tube cooling tubes with a 5mm fin height, which are seam-brazed for improved heat transfer and durability compared to traditional welded tubes, ensuring reduced recovery time between aggressive driving cycles.\n\nThe radiator is 100% TIG welded for maximum strength and longevity.\n\nThis radiator upgrade is listed as OE Part Interchangeable with 8W0 121 251 H. For further cooling performance improvements on B9\/B9.5 Audi S4\/S5 models, 034Motorsport also recommends pairing this radiator with their Auxiliary Radiator Upgrade Kit.","brand":"034Motorsport","offers":[{"title":"Default Title","offer_id":52686640054584,"sku":"034-102-1005\/7","price":800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687883222.webp?v=1784875547","url":"https:\/\/store.motormia.co\/products\/ea839-all-aluminum-radiator-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
