Over repeated thermal cycles, aggressive operating pressures (often exceeding 1.4 to 2.0 bar), and elevated under-hood temperatures from forced-induction powerplants like the \u003cstrong\u003eN20\u003c\/strong\u003e, \u003cstrong\u003eN55\u003c\/strong\u003e, and hot-vee \u003cstrong\u003eN63\u003c\/strong\u003e, the stock plastic embrittles. Micro-fissures routinely develop along the crimp seams and the upper radiator neck, causing sudden coolant dumping, thermal runaway, and expensive engine block or cylinder head warping.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upgraded performance unit eliminates failure-prone plastic entirely, utilizing heavy-duty, 100% TIG-welded aluminum end tanks fused to a dense, brazed aluminum tube-and-fin core. The increased fin density and optimized fluid passages accelerate heat rejection, counteracting heat soak during extended high-speed cruising or aggressive driving. Precision-fabricated inlet and outlet ports retain factory-style quick-disconnect geometry for a leak-free seal with OEM hoses. Directly replacing OEM part \u003cstrong\u003e17117612994\u003c\/strong\u003e, this radiator bolts into the stock core support mounts with zero chassis cutting or bracket modification required.\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;\"\u003e2011-2016 BMW 5 Series\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\u003eN20\u003c\/strong\u003e, \u003cstrong\u003eN55\u003c\/strong\u003e, \u003cstrong\u003eN63\u003c\/strong\u003e \/ \u003cstrong\u003eF10\u003c\/strong\u003e, \u003cstrong\u003eF11\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;\"\u003e240 - 445 hp \/ 260 - 480 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\u003cstrong\u003e17117612994\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2016 BMW 5 Series (528i, 535i, 550i) 2.0L, 3.0L, 4.4L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the F10 5 Series?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2011-2016 BMW 5 Series equipped with the \u003cstrong\u003eN20\u003c\/strong\u003e, \u003cstrong\u003eN55\u003c\/strong\u003e, and \u003cstrong\u003eN63\u003c\/strong\u003e engines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this radiator require aftermarket coolant hoses or modifications?\u003c\/strong\u003e\u003cbr\u003e No, it features factory-dimensioned mounting brackets and OE-spec quick-connect hose fittings for direct bolt-in integration.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet rigorous German performance standards, this cooling upgrade preserves closed-loop temperature control, preventing thermal throttling while retaining full compatibility with your BMW factory sensors and auxiliary cooling circuits without triggering trouble codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593807433976,"sku":"DS-E27ES1T79","price":194.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-bmw-5-series-2011-2016-2-0l-3-0l-4-4l-1.jpg?v=1790051745","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-bmw-5-series-2011-2016-2-0l-3-0l-4-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
