Decades of heat cycles make these composite tanks brittle, leading to micro-cracking, gasket leakage, and neck separation under pressure. In addition, the high-RPM profile of the naturally aspirated S14 generates severe thermal loads that easily exceed the capacity of aging, scale-restricted stock cores, inducing heat soak and elevated coolant temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis all-aluminum performance radiator eliminates failure-prone crimped plastic seams with hand TIG-welded end tanks fused to a brazed dual-row tube-and-fin core. Constructed from high-grade aluminum, the core increases fluid capacity and external cooling surface area without restricting air pass-through to downstream components. The reinforced design resists thermal shock and internal system pressure spikes during aggressive driving.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1988-1991 BMW M3\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eS14B23 \/ E30\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e192 hp \/ 170 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e17111468084\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1988 BMW M3 Base 2.3L L4 Gas (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1989 BMW M3 Base 2.3L L4 Gas (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1990 BMW M3 Base 2.3L L4 Gas (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1991 BMW M3 Base 2.3L L4 Gas (Manual Transmission)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eManufactured to critical tolerances, this unit installs into the factory E30 mounting provisions and retains OEM fan shroud positioning and hose geometry to guarantee dependable, leak-free operation on high-strung European powertrains.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50497371078904,"sku":"DS-EA3PZB47T","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-bmw-m3-1988-1991-2-3l-manual-1.jpg?v=1789260540","url":"https:\/\/performancechiptuning.com\/fr\/products\/aluminum-radiator-for-bmw-m3-1988-1991-2-3l-manual","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
