Over time, the continuous thermal cycling from the high-output 4.8L and 5.0L V8 engines causes the factory plastic to become brittle, eventually leading to micro-fractures, coolant leaks, or catastrophic tank blowouts. Furthermore, the standard-issue factory core lacks the fluid capacity and thermal mass required to efficiently manage heat soak during spirited driving or extended idling, resulting in elevated engine operating temperatures that compromise both performance and head gasket longevity.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis performance radiator resolves the OEM vulnerabilities by utilizing a 100% TIG-welded, all-aluminum construction that completely eliminates failure-prone plastic components and epoxied seals. Built with a robust 40mm thick, dual-row core, this unit drastically increases coolant capacity and expands the active surface area for superior heat dissipation. The core is constructed using an advanced vacuum brazing furnace process, ensuring optimal fin-to-tube thermal transfer without the insulative properties of traditional epoxy. The heavy-duty aluminum end tanks are precision TIG-welded to handle significantly higher systemic pressures, providing a permanent solution to thermal instability and safeguarding your engine against overheating.\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;\"\u003eBMW Z8 \/ Alpina Roadster\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;\"\u003e4.8L V8 (M62\/F5\/S62) \/ E52\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;\"\u003e375 hp \/ 383 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\u003eALPINA B10 (E39) 3.2 i | Engine: M60B30 (308S6K) | 191 KW \/ 256 HP | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eALPINA B10 (E39) 3.3 i | Engine: M52B28 (286S7T) | 206 KW \/ 276 HP | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eALPINA B12 (E38) 5.7 i V12 | Engine: M70B57 (5714KA) | 306 KW \/ 410 HP | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eALPINA B12 (E38) 6.0 i V12 | Engine: M73B54 (5412AG) | 316 KW \/ 424 HP | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eALPINA ROADSTER (Z8) 4.8 i | Engine: M73B48 (488S12) | 280 KW \/ 375 HP | 6\/2000 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 5 E39 (95-) 535 i | Engine: M62B35 (358S1) \/ M62B35 (358S2) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 5 E39 (95-) 540 i | Engine: M62B44 (448S1) \/ M62B44 (448S2) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 5 E39 (95-) M5 | Engine: S62B50 (508S1) | 7\/1997 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 7 E38 (94-) 735 i | Engine: M62B35 (358S2) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 7 E38 (94-) 735 iL | Engine: M62B35 (358S2) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 7 E38 (94-) 740 i | Engine: M62B44 (448S1) \/ M62B44 (448S2) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 7 E38 (94-) 740 iL | Engine: M62B44 (448S1) \/ M62B44 (448S2) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 7 E38 (94-) 750 i | Engine: M73B54 (54122) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW 7 E38 (94-) 750 iL | Engine: M73B54 (54122) | 9\/1998 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW Z8 E52 (00-) 4.9 | Engine: S62B50 (508S1) | 6\/2000 -\u0026gt;\u003c\/li\u003e\n  \u003cli\u003eBMW Z8 E52 (00-) ALPINA V8 | Engine: S62B50 (508S1) | 6\/2000 -\u0026gt;\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for exacting European standards, this all-aluminum radiator provides a drop-in precision fit for the E52, E39, and E38 chassis.
