The original equipment utilizes plastic end tanks crimped to a thin aluminum core. After years of heat cycling, the plastic becomes brittle, leading to micro-fractures, coolant leaks, and catastrophic failures at the upper radiator neck. Furthermore, the standard single-row core lacks the necessary fluid capacity and surface area to effectively dissipate heat during spirited driving or heavy traffic, inevitably leading to engine heat soak and compromised performance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty performance radiator eliminates the inherent flaws of the OEM design by utilizing a fully TIG-welded, all-aluminum construction. Featuring a robust 1.65-inch thick, 3-row core design, it increases total cooling capacity by approximately 30 percent compared to the standard factory unit. The 17.24\" x 17.32\" core maximizes thermal exchange efficiency, ensuring stable operating temperatures even under sustained high RPMs. Paired with a 16-inch, 10-blade electric puller fan generating over 850 m³\/h of airflow at 2250 RPM, this system guarantees optimal airflow dynamics through the fins, effectively mitigating heat soak in both daily commuting and performance applications.\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;\"\u003e1991-2000 BMW 3 Series, Z3\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;\"\u003eM42, M44 (L4) \/ E36, E36\/5, E36\/7\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;\"\u003e138 hp \/ 133 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1991-2000 BMW 318i (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1991-2000 BMW 318is (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1991-2000 BMW 318ti (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1991-2000 BMW Z3 1.9i L4 (Manual Transmission)\u003c\/li\u003e\n  \u003cli\u003e1991-2000 BMW Z3 2.0i L6 (Manual Transmission)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for proper fitment in the E36 engine bay, this direct-replacement cooling upgrade maintains standard mounting geometry while providing superior thermal management, keeping your European powerplant running at peak efficiency without triggering dashboard warnings.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50062553776376,"sku":"DS-EWK55OCRP","price":299.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-bmw-318i-318is-318ti-z3-1991-2000-1-9l-l4-1.webp?v=1785168188","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-bmw-318i-318is-318ti-z3-1991-2000-1-9l-l4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
