This radiator cools the water flowing through the charge air cooler, and that water in turn dissipates heat from the charge air before it enters the engine. It's evident this system needs increased cooling capacity to prevent heat soaking, the factory unit quickly heat soaks under pressure, leading to elevated intake air temperatures and inconsistent power delivery during demanding driving.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003edo88's replacement directly addresses this with a \u003cstrong\u003e66% larger core volume\u003c\/strong\u003e than the factory unit, using a dual-row, 48mm thick design for genuinely increased cooling surface area. A \u003cstrong\u003etriple-pass layout\u003c\/strong\u003e allows water to pass through the radiator three times rather than the factory's single pass, maximising core surface area utilisation for more effective heat rejection. Full aluminium construction with durable TIG-welded end tanks delivers genuine long-term durability and heat dissipation, making this a sound upgrade for track use, spirited street driving, or tuned B58 engines.\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 factory components.\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=\"mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This Front Mount Heat Exchanger\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\"\u003e66% larger core volume than the factory unit\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDual-row, 48mm thick core design for increased cooling surface area\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTriple-pass layout, water passes through the core three times versus the OE's single pass\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFull aluminium construction with durable TIG-welded end tanks\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCombats heat soak during demanding driving conditions, stabilises intake temperatures\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSuitable for track use, spirited street driving, or tuned B58 engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"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\"\u003eBMW F20\/F21 M140i\/M140iX (B58 Gen 1)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F22\/F23 M240i\/M240iX (B58 Gen 1)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F30\/F31\/F34 340i\/340iX (B58 Gen 1)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBMW F32\/F33\/F36 440i\/440iX (B58 Gen 1)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"do88","offers":[{"title":"Default Title","offer_id":54462617452877,"sku":"WC-420","price":711.76,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/4808\/2253\/files\/do88_BMW_B58_Gen_1_M140I_M240I_340I_440I_Front_Mount_Heat_Exchanger.webp?v=1786360120","url":"https:\/\/i6tuning.com\/products\/do88-front-intercooler-radiator-bmw-seria-f-b46-b48-b58","provider":"i6 Tuning","version":"1.0","type":"link"}
